A serial killer is to be released from a New Jersey prison based on a plea bargain made twenty-five years ago. Philadelphia homicide is asked to locate a potential crime committed while the killer was living in Philadelphia during the summer of 1977. A doorman was found strangled to death in a subway station in full uniform. The plot follows an evening at "The Rocky Horror Picture Show" involving the doorman, his girlfriend and the future serial killer. Valens received word from NYPD that his girlfriend was involved with credit card fraud and there's a warrant out for her arrest.
