Suffering from psychotic depression, a woman named Lisa (Andrea Marcovicci) witnesses the murder of her boyfriend. Making matters worse, the killing was committed by one of Lisa's closest friends, who has always carried a torch for her. Kojak (Telly Savalas) tries to determine the name of the guilty party, only to find that Lisa has blotted out all memory of the murder--while the perpetrator weighs the option of adding Lisa to his list of victims. ~ Hal Erickson, Rovi
