Merchant Madsen's 19-year-old daughter Amanda is planning to run away from her family's holiday and Madsen himself is at odds with one of the locals when he runs some chickens down. This year there is a new girl on the staff; 18-year-old Fie going to be a kitchen maid, but is immediately promoted by the hotel host. This arouses indignation from one of the other maids who decides to work against Fie.

Amanda has a bet with her friend in Hornbæk about who first debuts sexually, so now she is quickly trying to find a man. Her father is more concerned with getting her married well and sees his chance, as a Count's family moves into the hotel. One of the maids has a nocturnal visit from a young man which is strictly prohibited and hotel host Julius Andersen is determined to find out which of the girls it is. Andersen's morals are less important when he sees his chance to look through the keyhole when the young girls bathe. And then Royal actor Edward Weyse is suddenly summoned to a secret rendezvous in the summer night.

Fie dreams that her father has became ill and falls. She wants to leave her place as maid and go home, but it's not easy to tell Mrs Andersen or the young man Morten, who has been interested in her. Amanda has other plans. She is determined to win the bet over who is first with a man and does everything possible to get to a party at one of the big hotels in Skagen. Her father's interest in the young Count Ditmar gives her unexpected help. And then the hotel host gets an urge to look through keyholes, while the young girls bathe.

It has rained and stormed for two consecutive days and the guests are starting to get on each other's nerves at the Seaside Hotel. Weyse has an argument with the theater about the cast for next year, and Amanda will be persuaded to take a trip to Skagen with Count Ditmar. Mrs. Andersen must cope with the operation of the hotel alone, now that Mr. Andersen is in the hospital after the accident with the electricity, and it is quite a challenge for Molly Andersen, who has never had anything to do with the finances.

The small seaside hotel prepares for Mr. Andersen's funeral, but not all the guests think it is compatible with a holiday. For Molly Andersen, it's a sudden challenge to bear the whole responsibility for the hotel. Can she manage both guests and girls, and will she be allowed to keep the hotel right after her husband's death? Fie helps where she can, but Morten does not make it easier for her, as he once again provokes merchant Madsen. Yet it will be a very special evening at Andersen seaside hotel, where a summer night turns out to lure guests to unfamiliar adventure. And not least the awkward bachelor Adam gets an unexpected experience.

Summer is coming to an end at the resort and guests are preparing for parting with the sweet holiday life. Fie is invited to stay for the winter, but is in doubt because of the relationship with Morten. Mrs. Fjeldsø makes a last desperate attempt to find a suitable match for her son Adam, while Weyse abandons his desperate hunt for Mrs Aurland and learns something new about women's psychology. Merchant Madsen sees through Count Ditmar, but still hopes that he will be his son-in-law. Everything is bright until Ditmar's tormentor suddenly shows up at the hotel and threatens to expose the young Count's past.

The summer of 1929. The regulars from Copenhagen are back at Andersens Badehotel by the North Sea. Wholesaler Madsen's daughter Amanda is also arriving after a trip abroad, which was arranged by her parents to get her away from an unfortunate romantic connection. The maid Fie looks forward to Amanda's arrival with mixed feelings. The Grosserer daughter is the only one who can help Fie's boyfriend, Morten, free from the accusation that has kept him on the run for a year. But will she? And then two young men move into the hotel laden with a gramophone and jazz records in search of adventure.

The hotel is turned upside down to get ready for Amanda and Count Ditmar's engagement party. There are high expectations, but not for Max, who has a great desire to see Amanda say yes to someone else. Molly Andersen has picked up extra help at Hotel Udsigten, but there is smoke in the kitchen, as it turns out that the borrowed maid Jenny has just married the cook Martha's boyfriend. Weyse tries new means in his attempt to seduce office manager Aurland's wife, while Amanda has to remind her father of what he promised in return for her engagement. And Fie finally sees Morten again after a whole year.

Ten years after he left in anger, the late hotel landlord's son, Poul, returns home from America to end the inheritance case with Mrs. Andersen. The girls in the kitchen wonder what really happened between the serious young man and his father, and whether he has come now because he wants to take over the hotel. Amanda has put her father on ice until he keeps his part of the deal and acquits Morten, but then she suddenly discovers a secret that can solve the problem completely without the help of wholesaler Madsen. Mrs. Aurland is distraught over her relationship with actor Weyse and decides instead to seduce her husband.

Molly tries to borrow extra money for Poul's inheritance share, but gets "no" from the bank. When a buyer signs up to take over the hotel, Fie thinks it's time Poul knows what he's exposing Mrs Andersen to. The female guests are tired of their husbands' indifference and take a trip to Skagen, but the gentlemen prove to be fine to run a party without them. Morten returns home free of all charges, so Fie and he can finally be together. And Amanda and Max are caught in a thunderstorm, while little sister Vera and Miss Vetterstrøm try to get in touch with the deceased hotel host.

Molly has been promised she can continue as a tenant and keep her girls, even if grocer Damgaard buys the hotel. However, it quickly turns out that the grocery couple does not have the purest flour in the bag. Mrs. Fjeldsø is shocked by a letter from her son in Sweden, so her sister Lydia must use unconventional means to find out what has happened. Madsen is gripped by stock fever after big gains in the American market, and Poul finally finds his youthful love. In the kitchen, things also happen when Edith gets an idea of how she and the other girls can prevent Mrs. Andersen from signing the grocer's sales agreement.

In the penultimate episode, summer sings the last verse, and it has become the hour of truth for both guests and staff at the small hotel. It's getting harder and harder for Morten to hide from Fie what he's making a lot of money on. Helene Aurland has to decide if she should tell her husband that the child she is expecting is not his but actor Weyse's. And Amanda and Max make plans for how they can meet after the holidays until the truth hits them too. Only Mrs. Fjeldsø is completely certain– she has been let down by her son Adam, and it is irreparable.

Madsen has made a splash on the New York Stock Exchange, so he and his wife rent the hotel to a private hunting party to celebrate a happy family event. Fie and Molly have been busy opening out of season and the girls are extraordinarily summoned. Amanda struggles with the melancholy of being back after breaking up with Max and finds a confidante in Fie, while the jealous actor Weyse fears he will get into an accident with his rival, office manager Aurland, in the middle of the hunt. But nothing goes as expected this October weekend in 1929, when it blows up into a violent storm.

It's summer again, and Mrs. Andersen and her girls open the beach hotel for a new season. It's 1930 and the world crisis is going on just outside the country's borders, but quite different things occupy the regulars. Wholesaler Madsen is struggling to get back on top after the bankruptcy last fall. Mrs. Aurland fears her husband will find out he is not the father of their newborn son. Amanda is back in her marriage to Count Ditmar, but still dreams of Max. And Weyse arrives in the company of a young acting student who turns out to be a girl with multiple talents.

A vagabond who has news about the missing Morten is treated to beer and brandy at the hotel and manages to impress one of the girls in particular. After the funeral of the old Count, Amanda and Ditmar return to the hotel accompanied by Ditmar's mother, who begins to understand Amanda's relationship with Max. At the same time, visits are expected from two fine gentlemen to assess whether the young Count is suitable to take over his father's hereditary place in the Danish Parliament. Madsen is diligently trying to find financing for his new construction project, while manufacturer Frigh is becoming more and more preoccupied with Mr Weyse's young acting student, Miss Kitty Hansen.

Madsen has pledged his wife's jewelery to raise capital for the new construction project which makes problems for their marriage, but Mrs. Madsen gets unexpected help when the secretive lawyer Kvist moves into the hotel. Amanda has moved in with Max in the summer cottage, but she's afraid that Ditmar will want financial support from her parents. Weyse does what he can to protect his young acting student Kitty Hansen from manufacturer Frigh's approaches, but must recognise that she is independent. Morten's old childhood home is suddenly sold, which gives Molly and Fie the opportunity to finally contact Morten.

Amanda and Ditmar have agreed on how to handle their pro forma marriage, but neither Ditmar's mother nor Max fully agree with that plan. Miss Vetterstrøm returns from Copenhagen, because she mistakenly believes that Mrs Fjeldsø is ill. The two sisters finally reconcile helped by a bottle of liqueur. Weyse is suddenly called to a meeting at the theater which has received an anonymous letter threatening his career. Fie's father moves into the small farmhouse where Morten lived which evokes old feelings in Fie, but the discovery of a naked man on the beach soon has her thinking differently.

Both Max and manufacturer Frigh suffer from the sorrows of love. Max because Amanda has put him on ice after he quarreled with Ditmar's mother. Frigh because the object of his longing, the young acting student Kitty Hansen, has returned to Copenhagen. But then the two gentlemen both receive a letter that creates renewed hope. Fie's father has moved into the homestead and is discouraged over his sad fate. Mrs. Andersen tries to cheer him up. It succeeds beyond all expectations. And in the middle of it all, the hotel is suddenly visited by Prime Minister Thorvald Stauning himself.

Manufacturer Frigh has visited Kitty in Copenhagen and decides to go back to the hotel to put his cards on the table. But how do you tell your wife that you're leaving her? Frigh seeks advice from actor Weyse who is most experienced in these matters. Meanwhile Max and wholesaler Madsen are impatiently waiting for an answer from the architectural competition that can start their business. For Mrs Aurland, on the other hand, the wait is over. If her husband as found out that he is not the father of their child, it is high time for her to talk it out with him, regardless of the cost. But then Weyse receives a long-awaited call that turns everything upside down.

It's now autumn. Edward Weyse has been fired from the theater and makes a living playing piano for silent films in a cinema. He is approached by Amanda, who has got a job as an assistant to the self-absorbed and choleric film director Gerhard Flügelhorn, who offers Weyse a role in his new film. The hotel opens out of season so that the final scenes of the film can be recorded there in peace and quiet. Unfortunately, the rumour of this exciting event has reached the old guests, so suddenly the film crew is no longer alone. Mrs. Andersen has become ill and is staying with Fie's father who is sure she will be better off if she is told Morten her big secret.
