Black-market babies in a British boardinghouse provide the basis of this brutal crime drama. Though the landlady is outwardly upstanding and self-righteous, she is really the brains behind the operation. Her newest tenant is the pregnant lover of a convicted killer who has come there to avoid publicity. There the hapless girl is horribly mistreated as are all of the "guests." But despite the abuse, the young woman refuses to report it. Another boarder, who lost her baby due to the landlady's refusal to call a doctor, becomes the young woman's friend. Eventually things become so bad that a houseworker phones the police. Just before they arrive, the evil landlady shoves the pregnant woman down a flight of stairs and leaves her there to die. The wicked woman is then arrested and goes on to get her just desserts. This film received the very first British "X" rating.
