Porno (1990)

Michał, a mature man and father, is full of bitterness, regret, and longing for unfulfilled youthful dreams of true love. He reminisces about all his past lovers. With his first, Asia, he went on a seaside camping trip. He was 19 at the time, and she was two years younger. Despite his unambiguous advances, the girl resisted for a long time. Eventually, however, she gave in. For Michał, it was the proverbial pebble that caused an avalanche.
