Cops swarm a Central Park crime scene where a cold corpse sits in a hot car. The victim is a Jane Doe, shotgunned elsewhere and driven to the park in the stolen sedan. Veteran cop Corrigan (Walter Kinsella) and Tobin (John Miles), a university-trained rookie Corrigan dismisses as "Louis Pasteur," are charged with finding both whodunit and who the victim is. And from a tattoo on the victim's arm to sand-packed shotgun casings that defy ballistics analysis to a blade of a rare type of grass found in the car, the cops pull a case together. Science of the era does a ridealong with our detective heroes in this trim yet event-packed B-movie police procedural directed by Edward J. Montagne, producer of the Man Against Crime TV series.
