Karl Wieser, the Zurich tram driver, is a henpecked husband. When he is chosen to give a demonstration ride to foreign experts, he gains favor with his wife Anni. The mother is also particularly proud of Helen, her older daughter in America, who has made a good match, her younger sister Inge, who is destined to become a world-famous singer, and her son Herbert, who is studying medicine. But it turns out that she is succumbing to her own delusions and deceit.
A tramp tries to trick the community into paying for the funeral of his fellow tramp who was found frozen to death.
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.
