Lån mig din kone(1957)

Sales manager Lund sees an opportunity to become deputy director at the baby equipment company where he works. Unfortunately, he has neither a wife nor a baby. These are qualifications that both his boss and a rival colleague consider essential. Lund therefore pretends that he has been married for a long time. However, this little white lie has unforeseeable consequences when his boss invites Lund and his wife to dinner. Lund has to find a wife to borrow, and the complications unfold at a furious pace.
