Swamp Diamonds is the family-trade title for the sweaty Roger Corman crime melodrama Swamp Women. Policewoman Carole Mathews dons her torpedo bra and tight jeans to infiltrate a dangerous all-female criminal gang, currently serving time in a Louisiana Prison. The ladies escape and head to the swamp, where they've hidden a fortune in diamonds. Along the way, they kidnap geologist Touch Connors (later known as Mike Connors). For a while, it looks as though the girls will get away with their perfidy and Connors will end up as alligator bait, but Mathews saves the day. The supporting cast of Swamp Diamonds is a roll-call of 1950s "tough broads": Marie Windsor, Beverly Garland, Susan Cummings, Jil Jarmyn. Watch for Jonathan Haze, future star of Little Shop of Horrors, and Ed Nelson, future talk-show host and politician, in minor roles.
