On the 4th of July, a rookie female cop partners with a veteran detective to save the life of a high-school student from a radicalized serial killer.

In the late 1940's, Martha Beck and Raymond Fernandez were America's notorious "Lonely Hearts Killers". Their lethal scam was simple; they would swindle and then viciously murder lovelorn war widows who would answer their personal ads in which Ray would describe himself as a sexy Latin Lover. Ironically, Ray's initial introduction to Martha was as a prospective mark. But when they met, it was love at first sight, perhaps as a result of their penchant for kinky sex and their mutual love for duplicity and easy money. With Martha posing as Ray's sister, they bilked elderly spinsters and widows of their savings and then viciously murdered them in a bloodbath of sexual frenzy. When they were arrested, Martha and Ray confessed to 12 killings, although it is believed the actual number is closer to 20. At their sensational trial, Martha and Ray cooed, held hands and seemed as though they could not get enough of each other. Their plea of not guilty by reason of insanity was rejected, and on August 22, 1949, the homicidal lovers were sentenced to death. After numerous appeals, they were electrocuted on March 8, 1951, side-by-side in Sing Sing prison.
