The injuries left him unable to work and the financial strain is taking a heavy toll on his marriage. Enter Cody Larson and the promise of 1.5 million dollars if Niles chauffeurs him to Seattle to retrieve a dead drug dealer's buried cash and narcotics. What entails is a weeklong trip into madness as Cody kills indiscriminately, and then after each murder explains his philosophy behind the slaughter. He calls it the Frostproof. He believes he is the antichrist and will soon rule the world; until their hellish journey takes an unexpected turn.
