The deal is simple. Buy the stolen drugs for almost nothing, sell them and make a bundle. For Ray and the others, it's the deal of their lives. For Heather, the rich girl, it's a ride on the wild side. Deep in the dark, abandoned warehouse, Speed, the dealer, counts the money. Outside, a black Mercedes pulls up...five killers step out. They want their drugs back and they don't want witnesses. Trapped in the warehouse, the horror begins.

After a routine drug deal turns bad, Heather is arrested and taken to a mental institution. Inside the asylum, Heather's mind plays tricks on her, and she becomes convinced that a plot is under way to murder her.
