When taxi business owner Max Vivaldi hires Danny Baveystock - an antique expert from an auction house in London - to come over to his home town of Mumbles, Swansea to value his bakelite telephone, his high maintenance family are less than impressed with the £200 estimated once fees have been deducted. However over dinner, Danny finds a much more interesting case when Max recounts how a will of one his ancestors entitled the Vivaldi's to a stake of land that now constitutes the whole city, and as such makes Max the rightful owner of Swansea. Interested by the possibilities, Danny enlists the aid of his fellow London colleagues to work on verifying Max's claim.

Meanwhile Danny takes in the Swansea sites with Max's eldest daughter Maria, who takes him to the pub with her on the way to meet her boyfriend Gethin. But the evening is cut short when Gethin announces he has been having an affair with a woman at work and breaks up with Maria. Upset she goes to confront the woman the next day but

Eager to tell Val the news that the Vivaldi clan now own Swansea, Max is in for his own surprise when he arrives home to find Val's note announcing she has left him for another man. In panic, Max reseals the note pretending not to have read it. The next day Val discovers what has happened when she sees Max all over the news and hurries back home where Max pretends like nothing has happened.

Following the craziness of recent events, Max decides to drop his pursuit to have his father declared insane and instead publicly hands over the ownership of Swansea to his father and his new fiancé Big Claire, the latter of whom is soon handing over the inheritance in exchange for a house, a pub and to be named Lord Mayor. This is of little concern to Max who is still struggling to cope with the knowledge of Val's affair, especially as she refuses to name the man she ran away with. But he soon finds out for himself that Sam the Egg Man was her lover and responds by pelting him with his own eggs, an exchange that is secretly observed by Maria who is shocked to learn of her mother's infidelity.

Meanwhile, Danny is all set to leave Swansea now that Max has abdicated his ownership of the city but first decides to make one last ditch attempt to stop Rico from marrying Big Claire. However the visit has a less than desired outcome when Rico suffers a fatal heart attack. His death has a big i
