The low-budget 1970 sleeper is based on the true story of the grisly "Lonely Hearts" murders in the late 1940s. Tony Lo Bianco gives an excellent performance as Ray, a Spanish gigolo who meets lonely women through a mail club and swindles them out of most of their savings. Along comes Martha, an over-weight frustrated nurse (played perfectly by Shirley Stoler, who some may remember as Miss Stevie from Pee Wee's Playhouse), and then the brutality starts. Pretending to be Ray's sister, the two of them continue to seek out wealthy women to play their savage game with. One scene if very violent and a bit disturbing when, unable to kill one victim, Martha resorts to whacking her in the head with a hammer. Also in the cast is Doris Roberts (from TV's Everyone Loves Raymond). The same real-life killers were the basis for another film, "Natural Born Killers" (1994).
