The grim Boston-set tale begins as blonde tart Vivian Hedron goes to cheap bar and seduces Henry Shanway so she can swipe his car. She then speeds away to a remote beach to meet her lover James Harkley, one of the monied Boston Harkleys who is also very married. Just after Hedron tells him she is carrying his child, he shoots her and takes off clothes. After that, he throws her naked corpse into the ocean and Shanway's car into a local marsh. Time passes and Hedron's skeleton finally washes up on the beach. Lieutenant detective Morales is assigned the case. To learn the girl's identity, Morales enlists the aid of a medical expert from Harvard. They later discover that she was pregnant while searching the sand around her body and finding bones from the fetus. The police also dredge the swamp and find Shanway's car. Though he reported it stolen, he still becomes the prime suspect. Fortunately, the medical evidence does not support Shanway's guilt and Morales continues the investigation. Harkley has his own problems for Hedron's greedy landlady discovered Harkley's phone number in her late tenant's apartment and has also stolen the murder weapon. Armed with this proof, she begins blackmailing Harkley. Eventually, Harkley decides to kill the troublesome woman but finds both the detective and his wife Grace Harkley waiting for him. He escapes, but by this time it is too late and it is not long before justice is served.
