Jiří Svetozar Kupka

The film thematically follows the stories of the TV series "30 cases of Major Zeman". We can meet Major Zeman again with Lieutenant Colonel Zitny, Major Hradec and Lieutenant Gajdoš. The film is set in 1972 in a South American country and shows the activities of an international counter-revolutionary headquarters, which the central character of the film - Major Hradec - uncovers even at the cost of his own life. The film was largely shot in Cuba. The film is an edited version of the series episodes 27 and 28 "Messages from an Unknown Land" and "Hostages in Bella Vista".

Further east of the Dark Blue Sky, where the Heavenly Horsemen fought, the story of a Czechoslovakian fighter squadron takes place, to which Second Lieutenant Jandak arrives as a rookie. He then experiences both his first love and a battle high above the clouds in the collective of combat pilots. Combat pilots on the Eastern Front thus experience similar stories to their Western colleagues, with the same goals and plans and the same slim prospects of survival in their daily life-and-death battles. Not surprisingly, they fought at a time when they had a common enemy, characterised by the Messerschmitt aircraft.

A Czech ship's doctor accidentally meets his fellow expatriates on a tropical island. Under his influence, a sympathetic young woman, who has gone abroad with her sickly old father and her selfish and unprincipled husband, decides to return to her homeland...

Thirty Cases of Major Zeman is a Czechoslovak action-drama television show intended as a political propaganda to support the official attitude of the communist party. The series were filmed in the 1970s. Each episode encompasses one year, and investigations are stylized to that year. Most are inspired by real cases. The series follows the life of police investigator Jan Zeman during his career from 1945 to 1975.
