Keti goes to a prison to visit her daughter Elli, a young female prisoner, but Elli refuses to meet her mother. When Keti has left, the prison guard starts reading Elli’s diary, to find out what has brought Elli to end up in prison. Elli’s problems begin the day her mother gets divorced, and her mother’s young lover, Nikos, moves into their apartment. When Nikos tells Elli that he loves her furiously, and just pretends to love her mother, Elli is disgusted. Keti hears Elly screaming at Nikos, intervenes, and slaps Elli in her face. Elli packs her suitcase and leaves. A young man, Kostas, has fallen in love with her, but in vain. Elli is already in love with Yorgos, a guy who exploits women to obtain money from them for his obsessive gambling. After some weeks he is tired of Elli. To be able to rent a room, she starts selling her body to men she meets in restaurants. Kostas turns up, and they spend some lovely weeks together. When Kostas goes to Germany to continue his studies, Elli returns to her mother’s home. Alone with Nikos in the apartment, Nikos tries to rape her. Elli gets hold of a paper knife, and stabs Nikos in his stomach. Without witnesses, who could confirm her story, Elli is sentenced to prison for homicide.
