Two deranged young men invade the home of a family who is on holiday and force them into a series of humiliating games, threatening to brutally murder them if they refuse to do everything they say.
One of the boys is so insanely creepy that he constantly smirks at the camera during the killings, brilliantly portraying the disturbing self-awareness of an unhinged murderer.
You will definitely wonder if someone’s performance can really be that good or the actor actually has some issues in real life.
