The Jackhammer Massacre

After Mike's drug overdose death, Jack spirals into deep depression and addiction. He loses his job, develops a severe infection in his left arm, and becomes homeless, taking shelter in the warehouse where he works as a security guard.

He remains homeless and takes shelter in the warehouse, where he continues to struggle with addiction and paranoia. The isolation and deterioration define his daily life as he drifts between security duty and withdrawal.

One night, two drug dealers break into the warehouse to rob it because Jack owes them money. They intend to kill him since he cannot pay.

The dealers inject PCP, heroin, and crystal meth into Jack, triggering a paranoid psychotic break. He experiences a haunting vision of Mike and becomes unhinged.

In his delirium, Jack wields an electrical jackhammer in the warehouse's machine shop and kills the two dealers. The violence marks a turning point as his grip on reality fractures.

After Jack had phoned for money, his sister Tori and her girlfriend arrive at the warehouse. Jack traps Tori in a storage room and murders her girlfriend in a violent, chaotic confrontation.

Following the confrontation with Tori, Jack murders his boss who had come by to say the building had been sold. The act intensifies Jack's downward spiral as hallucinations continue.

In the morning, Jack experiences a flood of hallucinations and collapses in the street. He then murders the realtor and the buyer his boss was going to meet.

A cleaning crew hired by the realtor arrives; Jack kills two crew members, incapacitates one with a drug injection, and chases the final member through the warehouse to the roof.

The chase moves to the warehouse roof after the final crew member is pursued. The extension cord to the jackhammer becomes unplugged, and Jack tries to strangle Sam. Tori intervenes and knocks him off the roof with a piece of the discarded jackhammer.

Jack lies bleeding in the street as the hallucinatory Mike appears and yells at him to get up. The visions linger as reality remains blurred and uncertain.

Sam and Tori exit the warehouse, screaming at the sight that Jack is gone. The scene closes with the fallout of the night's violence and the eerie sense of his disappearance.
