At a fancy banquet, a successfull man, Pete, is verbally attacked by his drunk son. And it seems his entire family are having one complaint or another. Later, he dies during a jogging trip.

When Pete's sent back by Othniel (as a priest), he soon has to come to terms with his younger self's problems - he loves one girl, but another claims that he's the father of her unborn child, and that's who he married in the future he knows. But can he convince his younger self to marry the other girl, a poor Latin girl, with other means than disclosing the terrible secret he has been hiding for himself all these years?

Mrs Edwina Lewis is filled with joy when Othniel sends her back, so that she can satisfy her curiosity about a man she once had the chance to have an affair with - and didn't. Jones isn't equally thrilled.

But perhaps her marriage was better than she thought...

Ron, clerk at a publishing house, has a hard time at his job, and on top of this, his own daughter, Kaitlin, won't give up her unborn child so that she can continue study, but instead wants to live in her boyfriend's garage. Ron blames this on his wife, Tammy, who he thinks should have stayed at home with Kaitlin, while she was a baby. Soon however, Ron trips on a book and dies.

Othniel sees that Ron is serious in his regrets and sends him back in time, as a handy-man, a joiner. It doesn't take long for Ron (now Randy) to try to get Tammy to be a stay-at-home mom, but before he has a chance he discovers the reason why Kaitlin is so shy - because nobody cares about her, not even her nanny. So Randy spends some time with her. When it's time to leave her with Tammy he discovers that she is very good at her job, and that she's up for a promotion.

The only problem now is to convince himself that, in spite of what people might think, perhaps it better for him to stay home with Kaitlin...

Musical composer Tom Lasky is constantly bothered by his neighbour Harry, and doesn't notice that the gas oven doesn't work properly. After he is gassed to death, Tom finds himself at Othniel, who shows him that Harry dies without Tom's help. Tom is returned as a hobo, only one hour before he dies, but Harry disturbs the rescue attempt, and they are put in a mental institution together. Tom gets in two uncomfortable positions: advocating Harry in front of himself, and living beyond his first death. But can he persuade himself to turn into his ""brother's keeper""?

Ray, a firefighter with an outstanding record dies at the hand of his own son Richie. Ray's problems with his son began when Richie beat up another boy and Ray then covered it up.

Mr Smith, who had died in a fire Ray had fought, is his newly appointed guide - and not a very willing one.

Bitter recluse Nancy, who cares more about her cats than about people, ironically dies from being hit in the head by a cat statue. Othniel wants to give her a second chance to learn to like people, and takes her back to the orphanarium, where she used to dream about being adopted by the perfect mom from her favourite movie. Instead she had this harsh adoption board attendant, who hates cats.

While her guide Mr Smith is taught a lesson in humility, and maybe something about himself, Nancy tries her best at getting her younger self adopted by the seemingly perfect woman. But things aren't always the way they seem... or how we remember them.

Rhonda, a divorced mother, discourages her daughter Molly from going out with a man she just met, because ""he's a man."" When Rhonda's hate for men causes her death moments later, Othniel argues that Molly will be alone her entire life, unless Rhonda goes back and somehow makes Molly open to love again.

Rhonda agrees, but to her surprise, she comes back as the manager of a matchmaking company.

But Molly isn't the only one who's having problems with love - and Rhonda doesn't even see that her friend, the baker Zeke is in love with her. Before he has the chance to tell her, Rhonda's ex-husband (who left her 11 years ago) comes back - and proposes! Neither Zeke nor Molly can understand it when Rhonda says yes...

Finally, after a number of matchmaking attempts have failed, it's a cake that changes everything.

Mark and Mindy were married young and fought for the rest of their life until their car crashes during one of their arguments. Both Mark and Mindy must go back to find out the real reasons behind their failed marriage.

They are sent back to their honeymoon, as proprietors of the hotel, and as both claim that it was a tennis match that started the resentment, they try to stop Mark's back injury which happened during the match. They fail, and the newlyweds spend the honeymoon separately: her in the dining room and he in the hotel room. During that day they discover the real reasons behind their failed marriage: a fake diamond ring, and a call from a former lover.

Young Mark and Mindy break up. But as Mr Smith tells them: It's not over till the fat lady sings...

After a brief appearence at a school, Charlie - a gang member in the 1930s and 1940s - is killed. Othniel tells him that he has redeemed his bad ways ever since, but that he can get a second chance anyway, to solve his conflict with the love of his life, Rose.

Mr Smith follows Charlie back to Harlem during the Prohibition era, where Charlies interracial relationship to Rose is something strange and frowned upon. But the real problem is that Rose's father is with the FBI, and that Rose will turn Charlie in. Now Charlie must somehow convince himself to get out before the deal that will be raided by the FBI, or get Rose to not turn him in.
