Indestructible Man

Charles Benton, a double‑crossed robber, is executed in the Los Angeles gas chamber to end his criminal reign. His body is secretly slated for use by a scientist seeking to test cancer research and tissue rejuvenation. The illicit transfer sets in motion a nightmarish plan that will haunt the city within days.

Benton's corpse is delivered to a scientist who plans to study cancer treatment and tissue rejuvenation by reviving damaged tissue. The body is subjected to chemical injections and massive electrical shocks to unlock regenerative processes. The lab teeters on the edge of science and horror.

Benton is revived but is mute due to electrical damage to his vocal cords. He emerges as an impregnable, super‑strong figure with rapidly growing tissue and skin nearly impervious to trauma. The transformation marks the birth of a terrifying vengeance.

The revived Benton murders the scientist and his assistant, eliminating witnesses and claiming his own freedom. The act reveals the deadly consequences of the experiments and sets Benton on a personal course of revenge. The city becomes aware that something terrifying has resurfaced.

Benton targets his two henchmen and the attorney Paul Lowe, the man who betrayed him in cahoots with the henchmen to steal his loot. He begins a rampage through Los Angeles to avenge himself and recover his money. The police are drawn into the case as bodies start piling up.

Before his capture, Benton had left a map to his hidden stash with his stripper‑girlfriend. She has since turned her life around and begun dating the detective who brought Benton to justice. The map remains a crucial thread in the growing citywide mystery.

A wave of mysterious killings draws the police into the case, then reveals that Benton’s reanimated form is behind the attacks. The department grapples with an almost supernatural killer and begins to connect the murders to the earlier bust.

Paul Lowe, fearing for his life after the henchmen are murdered, confesses to the police and reveals Benton’s use of the sewer system to evade detection and locate the stash. The confession closes some doors for the investigation and clarifies Benton’s path.

The police close in on Benton as he moves through the city, using his enhanced abilities to stay one step ahead. A tense pursuit unfolds through urban streets and sewer tunnels, culminating in a direct confrontation.

During the chase, Benton takes a direct hit to the solar plexus from a bazooka, leaving him severely wounded but still standing. The blast temporarily halts his rampage and accelerates his decline.

A flamethrower is used against Benton, burning him and driving him toward a power station. The flames intensify his vulnerability and push him toward a final confrontation.

Benton climbs atop a gantry in the power station as the apparatus is set in motion. He watches the police below without noticing the dangerous displacement he has triggered. The gantry pushes him toward a fatal miscalculation.

A dangling hook nears a transformer and sparks erupt through the metal framework, sending hundreds of thousands of volts through Benton's body. He is burned to ashes as the machine goes critical.

A few quiet days later, Detective Dick Chasen proposes to his girlfriend at a drive‑in hamburger stand, signaling a fragile peace in the wake of the terror. The city seems to have survived the 72‑hour nightmare and begun to heal.
