Just shy of his 40th birthday, music producer Tyler Harrison has started to experience horrific hallucinations. At first, he thinks it's just stress but the hallucinations continue, At a 3-day concert in Chicago he is approached by a man who tells him that he's going to die on his fortieth birthday. The man claims to be an angel and even though he gives Tyler enough evidence to convince him he's telling the truth, he doesn't know what to do with the information. Tyler's underlying doubt and confusion about Matthew's prediction turn to anger, both at God and those around him. As he begins to exhibit destructive behaviour, he befriends Ellis, an internationally known DJ. Tyler is scared that he really is about to die. He's scared for his sanity and he's scared that if he does die, he's not going to Heaven. He also soon becomes scared of Ellis, who is wild and opens up a door of temptation. As Tyler begins a downward spiral of fear and confusion, he reaches out to a pastor he met, Will, and tries to right his wrongs with some of the important people in his life in a desperate attempt to find peace before his 40th birthday.
