Edward G. Robinson heads an all-star cast in the life-and-death medical drama Operation Heartbeat, co-starring Kim Stanley, Maurice Evans, Kevin McCarthy and Shelley Fabares. Lawsuits fly when a widow (Stanley) believes a gifted surgeon (Richard Bradford) allowed her husband to die so his heart could be transplanted into the doctor's ailing mentor and friend (Robinson). Operation Heartbeat was the pilot movie for the TV series Medical Center.
