Producer Raymond Stross, whose company was named Eros Films, specialized in making movies with sexual subjects of all sorts (usually starring his wife Anne Heywood), and this one is all about prostitution in London.
Milly Vitale is quite impressive as an innocent Italian girl, just arrived in London who soon is lured into a degrading world of selling her flesh. She's naive in the extreme, and takes only four days to fall madly in love with a low-life pimp, well-played by Hollywood heartthrob John Derek (long before he became famous for his series of actress wives Ursula Andress, Linda Evans and Bo Derek), and soon become a hardened, disillusioned woman.
Script by Leigh Vance charts the inner-workings of small-time gangsters and everything seems hopeless until the final reel when Milly finally sees the light and is poised to testify in court against Derek.
Best scene comes when Derek finally blows up against the heroine he's been mistreating, and with his eyes bugging out in closeup he reads her the riot act in a terrifically negative outburst of pure misogyny.
