I don't want to give anything away, so I won't say too much here! What I WILL say is that the premise is brilliant and the execution makes the most of it. It's extremely well written, directed, and edited, and the performances are wonderful. If you're into dark comedies, thrillers, character-driven indies, and/or horror films (This movie excels in all of those arenas.), then check out "Killer Concept"!
