Overview:

A young waiter named Michal gets into trouble when he is robbed of his daily takings, which he was supposed to deliver to the bank. He's on probation, so it's clear that no one trusts him. So he asks for help from a friend, Tomáš, a taxi driver, who borrows from Adamec, a dangerous bellhop. By chance, the two friends manage to find out that his colleague Kadlec and his son-in-law, garage keeper Bures, who is a stolen car dealer, are involved in Michal's robbery. With the help of Michal's girlfriend Magda, they devise a scam to punish the extortionist boss and hand over the two seemingly blameless scoundrels Kadlec and Bures to the police with the evidence.
