Inspector Cadek from the 13th police station should keep an eye on the released safe-cracker nicknamed The Cat. He rightly suspects that Cat will go and pick up his last loot which the police didn't manage to find and that he will want revenge on Karta who helped get him behind bars. At the hospital, Cat's ex-lover Fróny hopelessly falls for doctor Chrudimský and decides to start a new life. She still refuses to help the inspector in his search for The Cat and Karta.
