Cab driver Hugo Meier is married to two women and lives at two addresses. He therefore lives according to a precise timetable. This has worked well so far. However, Hugo has an accident and can't get home. The two worried wives contact their police stations and ask for help. Two officers immediately do their duty and investigate. Hugo is now in dire need of help. With the not entirely voluntary help of his friend and neighbor Oskar Stöckli, Hugo leads the officers and the wives into a labyrinth of fantastic excuses and ludicrous lies. Harmless wives are transformed into hysterical bitches and well-meaning friends into hot-blooded, gay seducers.

Wanner, a man of independent means, has a mistress in Geneva. However, in order to spend a few days with her without risk, he decides to open a sales branch of a long-defunct company. He therefore hires a "trusted" employee in Geneva to look after the office premises, including the bedroom, and to provide his mistress with everything she needs. This arrangement works quite well at first, and Wanner enjoys this sweet diversion to the fullest until... well, until his wife wants to visit the branch and, above all, meet his business partner. Where can he conjure up a partner so quickly?

In a run-down hotel, only one room with two double beds is still available. The head porter, a former foreign legionnaire, and the shady hotel manager have double-booked this one room. First to an exhausted couple and then to a sales representative who is expecting his mistress, a dancer. But on this very day, his wife visits him as a birthday surprise. So now there are two couples and a dancer in one room, and even the pull-out folding screen is no solution. Everyone discovers a stranger, half-dressed, almost dressed, in the bathroom, in the beds, in the room.
