The story takes place in the small resort town of Chornomorsk in the Odesa region. It would seem that nothing can overshadow the measured life of this warm land. But not everything is so rosy. Poachers, sea pirates and smugglers frequent the waters, and the area is often visited by sea pirates and smugglers. Needless to say, boat racers disturb the peace of holidaymakers every day. Three policemen of the marine patrol - conscientious but conflicted Captain Kepa, erudite good guy Lieutenant Yegorka and Sergeant Sergik, an expressive, cheerful Odessa - will come together to protect residents and tourists from bandits and restore order on land.
