Synopsis

Skopec, Prouza and Petrtýl are three country plasterers who are working on the renovation of houses in Prague. They are tempted by the Prague night life, but their first visit to the luxury Diplomat Grill doesn't go too well and in the end they have to escape. But they refuse to give up. They have superior suits made for themselves and pay for training in social graces from the former dance teacher Dvorský. When Dvorský decides that they are already sufficiently well educated, the men set off again for the Diplomat Grill. Here they meet three young girls. They have no suspicion that these are girls of rather easy virtue, who are looking for rich men in the Diplomat Grill with a view to fleecing them.
