Patrick Lajonne returns to Munich unexpectedly from a year long contract in the USA. He discovers that his friend Jochen, who was looking after his lavish villa, has allowed three young women to live there. The women have been disappointed in love affairs and have decided to have nothing further to do with men. Patrick decides he can change their minds, and to do so he goes to live in the house with them, in the role of a woman, "Patricia". Apart from all the predictable problems with suspicious neighbours and work colleagues, Patrick develops a love interest with one of the women; and then her rejected boyfriend arrives on the doorstep.
