Rita Adams (Joan Woodbury) is a naive young girl with a difficult life (ex-convict father, no job et cetera) who takes the rap for her useless boyfriend Harold (Phillip Trent) after a hit-and-run. After a spell in the state pen she discovers the truth about her beau and sets out on a life of crime...
She becomes a mysterious "blonde beauty" and rises up the ranks in the mob led by Jack La Rue. Meanwhile Alan Ladd is an undercover agent who has infiltrated the mob. When he is ready to bring them down unfortunately Rita is ready to go straight...
It is a rather complicated plot and unfortunately tries to pack too much in to a rather short film. It is complete nonsense but is an enjoyable fast-moving romp.
