Architect Matti picks up Ritva and her young son while on a business trip. When the car runs out of gas, the travelers are forced to spend the night at a guesthouse, pretending to be a married couple. During the night, Ritva runs away, leaving the child in Matti's care. Matti tries to cope with looking after the child and keeps it a secret from his wife Maija.
