Dirty city (1965)

Mikes, the head of sanitation for a large city, is a ruthless blackmailer who pressures his wife Anna to divorce him so he can marry his mistress. Callous and insensitive as he is, he has made her life a living hell. Anna does not want to divorce him because she is pregnant with his child and fears social condemnation. One night, she is attacked by a man who tries to rape her, but she is saved by a passerby, Alexis.
