The problem proposed in REMOVAL is that Cole is quite overworked pulling double shifts all week, and his marriage is failing. He hasn't been taking his meds as prescribed, and when he doesn't, he tends to hallucinate. On top of this, his last estimate of the week ends up being a wealthy stiff (Oz Perkins / STAR TREK) who snobbishly demands to the lure of a $5,000 bonus that he complete the entire house and all its rooms tonight. Its a 3-man job, and Cole is tired and out of medication, but he reluctantly takes on the proposition.
Cole begins to become suspicious of his employer as the night progresses and his condition worsens. A crimson stained carpet, a shovel carried through the backyard, the mop and bucket by the locked room, the homeowner's detest for his missing wife. All coming to a head while begging the question - is Cole hallucinating, or is he about to be off’d after cleaning up a murder scene? With little time left, its a decision he must decipher through a fog of uncertainty that will have you gripped and grasping for straws of truth. In finality , as perplexed as you may become, its all ironed out for you in a manner reminiscent of SAW or SESSION 9 - circumventing duplication and drawing good qualities from those film's elements to artistically signature an ending it can call its own.
