Kolya and Vasylii learn that their father, who left them when they were children, is dying in Luxembourg, far away from them. One of them wants to go and find his father, while the other one does everything he can to prevent the first from leaving the country. As a result, they both go to Luxembourg in search of their dad: Kolya considers him a hero, while Vasylii thinks he is a scoundrel.
In the cartoon, Patron, just like in real life, searches for explosive objects and befriends other animals - in particular, Tom the Cat.
