The Boston Strangler

When a string of women in Boston start turning up dead, the police launch an investigation headed by John Bottomly (Henry Fonda). Through chance, Bottomly gets the evidence he needs to arrest Albert DeSalvo (Tony Curtis). Though DeSalvo denies having any connection to the murders at first, the police use hypnosis, pressured interrogation, and interviews with the only surviving victim (Sally Kellerman) to coax him into confessing. Still, whether he is truly guilty remains a mystery to many.
