It is the summer of 1945. A party of young people are enjoying the beginning of a new life to the full. For them this is the year one. One of them, law student Pavel, is more attracted to film than to law. With his eight-millimeter camera, he films everything that catches his attention. One day he captures an interesting face on film, a girl with an air of mystery. Pavel visits the girl, whose name is Helena, and meets hers and her elder energetic sister Olga. From Olga, he learns that the girls have spent the years of German occupation in a concentration camp and cannot forget the horrors they have lived through.

Ondrej lives on a farm outside a small town with his family. One day a group of men arrive at the family's house and the harmonious life they've led so far changes drastically for the worse.

Based on the only extensive prose work by the surrealist painter Josef Capek, Shades of Fern most resembles the philosophical fairy tales and fables of Josef’s older brother, the legendary Czech novelist and playwright Karel Capek. Two young poachers, more boys than men, kill a gamekeeper when they are caught illegally hunting. Panicked, they retreat into a forest that grows steadily more forbidding and deadly as their fear for the future—and guilt over their action—mounts. Loosely based on hundreds of oral folk tales and legends that haunt the woods of Czechoslovakia, Vlácil’s contemporary updating artistically underscores the relationship between man and nature, crime and punishment, isolation and society, and guilt and memory.
