An end-of-year party for an ‘alpha’ group of first year university students turns nasty when a game of ‘truth or dare’ ends in humiliation for ultra-rich social misfit Felix Hautbois. For five students at the gathering – beautiful Gemma, bitchy Eleanor, haughty Paul, bullish Chris and small-time dealer Luke – this seemingly minor incident will have unexpectedly devastating repercussions.
Some months later, the friends meet again at a surprise party for Felix. Arriving at a sprawling mansion, they make their way to an old hunting lodge where they encounter Justin, Felix’s older brother. Justin explains that Felix is late but he persuades the gang to join him in getting drunk.
But psychopathic rage bubbles beneath Justin’s charming exterior, and the real reason for the gathering is revealed: Felix has committed suicide, and Justin is determined to find out why.
A brutal game of ‘truth or dare’ ensues as the terrified hostages are questioned one by one, and cracks appear as the friends turn against each other in desperation. But it soon becomes clear that the whole truth of what happened has yet to surface – and that there is little chance that any of them will survive Justin’s ruthless interrogation.
