Hulking, soft-spoken lab technician Leo Kroll (Victor Buono) is burdened with low self-esteem and a domineering, wheelchair-bound mother (Ellen Corby). Oh, he's working out his issues. Trouble is, he's doing so by stalking young nurses, throttling them, and throwing his city into a panic. Exploitation chiller banged out during the course of the Boston Strangler's spree co-stars David McLean, Jeanne Bates, Davey Davison. 89 min. Widescreen; Soundtrack: English.
