The Grissom Gang (movie, 1971)

The Grissom Gang is a remake of the notorious 1949 British melodrama No Orchids For Miss Blandish. Kim Darby plays a 1920s-era debutante who is kidnapped and held for ransom. Her captors are the Grissoms, a family comprised of sadists and morons, and headed by Ma Barker clone Irene Dailey. One of the Grissoms, played by Scott Wilson, takes a liking to his prisoner, which results in a bloody breakdown of the family unit. Both The Grissom Gang and the original No Orchids For Miss Blandish were inspired by the best-seller by James Hadley Chase, though neither film retains Chase's original ending.
