Chamber of Horrors

Draco and Blount, proprietors of a Baltimore wax museum, become involved when Jason Cravette kills a woman and marries her. The duo assist the police in bringing Cravette to justice, who is convicted of murder and sentenced to hang.

During transport to be hanged, Cravette slices off his own hand to escape and vanishes. The police believe he is dead as he slips away with a hook in place of his hand and flees toward New Orleans.

With a hook hand and a new alias, Cravette hatches a plan to avenge those who betrayed him. He returns to the scene as a mysterious threat, bent on finishing his vendetta.

Cravette takes the prostitute Marie Champlain, transforms her into a refined figure, and brings her back to Baltimore. He orders Marie to seduce the judge who condemned him to lure him into a trap.

Marie succeeds in drawing the judge into Cravette's scheme, and Cravette kills him, then cuts off the judge's arms and head to destroy identification. The scene is left with the killer toasting the crime with champagne.

Draco and Blount discover the crime scene and deduce that the murderer is sending a body piece by piece. A mysterious blonde clue and the judge's fondness for women point to Marie as a key suspect.

The detectives trace Marie to her home and Draco asks Marie to pose for a wax model of the dead judge. Cravette overhears and nudges Marie to consent and to accompany Draco for a night out.

Cravette seizes Dr. Cobb, a witness who testified at his trial, murders him, and severs his hands, sending the evidence to the police with a cryptic note. Draco remains unaware until the crime is tied to Marie's story.

Draco and Blount realize the killer is delivering a corpse piece by piece and Marie recalls the hand-armed man she met in New Orleans, tying Cravette to the case.

Confronted by a wax dummy of the dead judge, Marie confirms that Cravette is the man she encountered in New Orleans, cementing Cravette as the mastermind.

A dragnet closes in as Cravette is apparently captured by Patrolman Rogers, but he kills Rogers with a pistol hidden in a mock hand and sends the arms to the police.

Cravette evades the police stakeout by entering the wax museum through the roof and knocks out Draco's allies one by one. He confronts Draco, demanding his head in a final showdown.

A brutal struggle ends with Cravette being impaled on his own wax figure. The weapon-free confrontation seals his fate and just before dawn the killer is destroyed.

In the aftermath, Marie receives a light two-year sentence. Draco and Blount discover that a female wax dummy is actually a real murder victim, prompting them to call the police.
