Cary Buchanan spent years trying to pull his son, Matthew, back from the edge, hoping his anger and instability would pass. But when his son begins threatening to kill him, he feels he has no other choice than to cut off all communication, believing the best way to put out a fire is to stop giving it fuel. For several years, his theory was right. Then comes the phone call he never expected. "Mom is dead... and Matthew did it," his daughter tells him. But Cary learns that's not all - he might be coming to kill him too.
