In this episode a museum worker (played by Martin Balsam) takes a set of wax figures into his home, where they begin to show the homicidal tendencies of the famous murderers they depict.
Martin Lombard Senescu, a gentle man, the dedicated curator of murderers' row in Ferguson's Wax Museum.
His boss and best friend, Ernest Ferguson, informs him that he has decided to sell the museum due to a long-term decline in attendance and his desire to retire.
They require an air conditioner to keep from melting, and due to the hot weather, the resultant electric bills quickly wipe out their savings.
After one last effort to convince Martin to return the figures to Ferguson's care, Emma sneaks out of bed one night and goes down to the basement.
Martin nervously claims to have gotten rid of the wax figures, which arouses Dave's suspicions when he hears the air conditioner hum and finds the basement door locked.
Suddenly, the wax figures come off their pedestals and advance on him, claiming he murdered Emma, Dave, and Ferguson even though he was not in the basement when any of them died.
