Wild Youth（1982）

Sifis, a young boxer, is going to challenge the Greek champion Vlassis Hristou, despite the opposition of his cruel, conservative father. His little sister Maria, a virgin teenager, gets pregnant after a romance with Lefteris. Her father reacts violently, because Lefteris comes from a destroyed family: his mother is a poor charwoman, his sister, Roula, a young harlot and his brother, Foivos, an ex-convict.
