Student Raskolnikow, who has written an article about laws and crime, proposing the thesis, that un-ordinary people can commit crimes if their actions are necessary for the benifit of mankind, murders an old woman, who operates a crooked loaning house, as well as her sister, who made the mistake of visiting her at the wrong time. He is suspected of the crime, but somebody else confesses to the murder. Meanwhile, he has fallen in love with Sonja, the street-walking daughter of an ex-official who was fired because of drinking. Raskolnikow's sister is engaged with an arrogant official, who dislikes him, because Raskolnikow gave Sonja 25 Rubel for her father's funeral. When Raskolnikow tells him his opinion of his behaviour against the poor, he tries to show he's a good guy also to the public and showing that Sonja is also a thief at the same time by framing her of a theft of 100 Rubels.
