Lorelai Mason (Joanna Miles) is the only witness when two brilliant but unbalanced psychology students, Casey Nystrom (William Katt) and Bob Viliano (Jim Borrelli), murder their professor and dump his body into the harbor. To prevent Lorelai from talking, the two cunning killers begin playing "mind games" with the hapless girl, the better to drive her insane. But Lt. Kojak (Telly Savalas) knows a few psychological-warfare tricks of his own. ~ Hal Erickson, Rovi
