The story of the film is based on the classical tale about seven naughty sons, whom their mother cursed in anger and thus turned into ravens. When their youngest sister grew up, she decides to find her brothers and to free them. However, she falls in love with a young Prince.
Marek (Jirí Holý), formerly a driver of a long-distance lorry, has served his term for smuggling art works abroad and is released from jail. Years ago, he sacrificed himself and confessed his guilt on behalf of his companions - the drivers Krása, Jelínek, Hess and Novák from the Ministry of Culture who gave them tips. Marek finds Hess and tells him that now he expects the gang to compensate him for the wasted years of his life.
