Two young men, indistinguishably alike, decide to swap. But with one a popular singer and the other a car mechanic, fitting into their new "life roles" is not easy. They experience more than one humorous situation and cause confusion. And how did it all start? Popular singer Vaclav Dubsky goes with his friend to meet his female fans. In a village inn, where he stops for lunch, he meets his perfect double - Joska, a car mechanic. Who wouldn't want to take advantage of this resemblance? Especially for the tired and bored Vasek, it's an opportunity to enjoy anonymity at least for a while. And so the young men swap...
