When Aino's good friend tells them she's pregnant, Aino and Micke begin to reflect on their own attitude towards starting a family: Do they want children? Is this a good time to try to have a child? Meanwhile, Aino has problems giving up smoking.

When Aino isn't pregnant after three months of trying, she consults Emma. Aino stops drinking coffee and alcohol and only asks Micke to give up cola drinks containing aspartame. Micke's parents, Gunne and Lasse, try to help in their own awkward way.

Eight months later Aino is still not pregnant, which has begun to affect her self-esteem. The pressing situation is not alleviated when Micke's big sister, Edith, who seems to be perfection itself, arrives on a surprise visit.

Worried about Jussi being in such bad shape, Aino asks Micke to take Jussi to play tennis. Aino tries to turn a new leaf by focusing on a new work project: she begins writing a novel about human rights lawyer Kristiina Havu, whom she greatly admires.

When Aino has finally become pregnant, they decide to tell their families only after the first trimester. On Christmas Eve, when the whole family has gathered to Aino's and Micke's home to celebrate Christmas, the couple's secret is constantly in danger of being revealed.

Aino's pregnancy is progressing nicely, but Gunne, who is very enthusiastic about her future grandchild, can't stop interfering with Aino and Micke's lives.

A very-pregnant Aino wants to enjoy her last remnants of freedom by attending her friend Sarah's party, and Micke reluctantly agrees to go with her. That same night, Lasse and Gunne invite Jussi over for dinner, but the mood is somber.

When Micke's well-off cousin Ponke gives him the chance to design a summer cottage on an island, Micke seizes the opportunity to work as an architect. Meanwhile, Aino tries to get everything ready for the baby.

At the final stretch of her pregnancy, Aino starts to fear that she will lose her professional identity due to motherhood. She promises to take on a work project shortly after giving birth, but soon has doubts about her decision.
