An astronaut (Steve Forrest) returns from a space flight to find things much changed during his absence.

After learning that the wax museum that he works in will be closing down effective immediately, employee Martin Lombard Senescu frantically convinces his boss to let him store the wax figures in his "Murderers Row" exhibit until a buyer is found. However, it doesn't take long for Martin to become convinced that they're capable of killing again, and when a buyer is found, a new wax figure is added to the mix.
