Dick Van Dyke stars as a doctor-turned-detective in this made-for-television medical thriller. Van Dyke stars as Dr. Mark Sloan, the ring leader of a small group of doctors who investigate the death of a U.S. Senator (David Richards) during surgery. Sloan has his own interest in finding out the cause of death -- his ex-lover (Suzanne Pleshette) is the prominent heart surgeon who was at the helm. Unfortunately though, Dr. Sloan gets more than he bargained for and stumbles onto a plot of revenge and murder. This two-hour movie was one of several which introduced viewers to Van Dyke's character and led to the popular TV-series Diagnosis Murder. ~ Bernadette McCallion, Rovi
