'They were originally five. Elliot. Brian. Tallis. Cameron. And Dylan - charismatic Dylan - the mediator, the leader, the man each one turned to in a time of crisis. Five close friends, bonded in college, still coming together for their annual trip to Las Vegas.
'This year they are four. Four friends, sharing a common loss: Dylan′s tragic death. A common loss that, upon their arrival in Vegas, will bring with it a common threat: one that will make them question who their departed friend really was, and whether he is even worthy of their grief.'
