Margaret Midas (Martha Scott) tells her philandering son-in-law Harold Van Wyck (Oskar Werner) that he is finished as head of the family-owned Midas Electronics Company and that her son Arthur (Robert Brown) is the new boss. Van Wyck prevents the purge by carrying out an intricate scheme to eliminate the woman, using to his advantage his highly specialized close-circuit TV security system.
Lt. Columbo (Peter Falk) attempts to prove Van Wyck’s guilt, but has trouble convincing Van Wyck’s unassuming invalid wife, Elizabeth (Gena Rowlands). (1975)
