A motley of vacationers on a bus headed for a week long vacation at a seaside resort. Among them: a single, moderately famous singer; a nerdy, onanistic man; a couple of old ladies reaching senility; a couple of young gals looking for an amorous adventure; a family with a boy unsure about where he fits sexually; a beautiful woman that, besides working as a trip guide, has pretensions of being a music composer; a couple of gay men; and another family where the parents are stuck in a sexual ice age while their twentyish daughter is looking to connect with a man.

The charismatic and self-confident man, Karel Král, is the editor-in-chief of men's magazine. Although a chauvinistic type, he is very popular with women. However, he struggles in his personal life. He frequently argues with his ex-wife over their 17 year-old daughter Julie, who despises his new way of life. Then the consequences of his behavior catch up with him. He loses his job, and the editor-in-chief position is given to a young and beautiful woman. But his bad luck does not end there. After another fight with his ex-wife and daughter, and a woman driver crashing into his car, Karel and his best friend Cestmír have an evening of binge drinking. During the wild night, he expresses a wish to be a woman. When he wakes up the next morning he discovers that his wish has been granted.
