Steamy chemistry, an instant pregnancy, and a full-blown disaster serve as the background for the relationship between Audrey ("a woman who smells extraordinarily good") and Frank ("a robust lover").

Audrey has to face reality and her new roommate: Frank. She introduces him to her brother, Patrick, who makes life royally hard for them. Frank reconnects with Dave, an old school friend, who has turned into a charming bastard.

Living in the Magdalen Islands, Audrey's parents visit her; their first meeting with Frank is not ideal. Other problems arise in Audrey's health, complicating her pregnancy and creating stress for the couple.

Audrey and Frank plan their wedding while Frank prepares a surprise party for Audrey's birthday. Frank is fired by his bosses and he begins to look for a job in Montreal.

Audrey, who is very far into pregnancy, picks up Frank at the airport and informs him that she has invited an old friend to be her Maid of Honor. Frank decides to ask Patrick to be his Best Man.

Audrey's hormones cause her to experience waves of sexual arousal and sadness, as well as a host of other worries. Frank has difficulty getting advertising contracts. Audrey meets an old flame by chance.

Audrey and Frank now have two children, a boy and a girl. They invite family and friends to come and celebrate the birth of the little one, but obviously everything is going wrong. Mia, Frank's mother, and Audrey are at loggerheads, while Audrey's father begins to lose his memory.

A new colleague who is too flirtatious excites Frank. Audrey feels out of place in the "mom-baby" course and she develops a dependence on another mother.

After news of Margot's separation, Audrey and Frank decide to take a romantic trip to Cuba that comes close to disaster. Bernard, who has just left Margot, frequents shady places.

Things are less difficult for Audrey and Frank - who are celebrating their wedding anniversary - than for their friends. Margot finds herself with a possessive lover; Bernard has a strange adventure; and Dave has an intense new girlfriend

Audrey decides to go back to work, but she has to control her nerves before meeting with the school principal. Frank has a huge problem with a co-worker and has to make a professional decision.

Frank and Dave hit the slums. It's a bit of a descent into hell for them. Audrey decides to go out to a bar, but she will have trouble remembering the events of the previous night.
