A group of teenage boys and girls find love and adventure during their summer holiday in this 1967 musical filmed behind the Iron Curtain in East Germany. The ten boys and eleven girls meet while hitchhiking to the beaches of the Baltic Sea, and their initial instinct is to terrorize each other with pranks. The two camps converge soon enough, however, for a series of mild flings. A love triangle emerges between a blonde party girl and two boys, leading to a fistfight and a joyride in a stolen fishing boat, but the authorities are forgiving of these youthful indiscretions and the groups remain intact. Heisser Sommer is packed with sprightly pop tunes, colorful dance numbers and an overall veneer of innocence that compares with the "Beach Party" films that were popular in America earlier in the decade. Two featured performers in the ensemble cast, Chris Doerk and Frank Schoebel, were major pop stars in their country at the time of this film's release, as well as husband and wife. Heisser Sommer was a huge hit in East Germany, and the video release features English subtitles for both songs and dialogue.
