Lån mig din kone.

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.

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.
