Home for the Holidays [1972] [DVD]

"Home For The Holidays", originally a made-for-television horror movie, is a neat little horror mystery that came a little before it's time. The plot centers around the Morgan family. Benjamin Morgan (Walter Brennan), a dying man, summons his four estranged daughters back home on Christmas Eve.

When the girls arrive, their father reveals to them that his current wife, Elizabeth (Julie Harris, of "The Haunting"), who was suspected of her previous husband's death, is poisoning him slowly, and that he essentially wants his daughters to murder her. ~ imdb
