Jay Austin is a "lip service" Christian (someone who claims to believe in Jesus, but doesn't act like it, a hypocrite in other words), who owns a used car lot. He lies to his customers and cheats them when he sells cars. He is a lousy husband and father and his marriage isn't going great. On top of this, his used car business is $32,000 behind to the bank, who threaten to repossess all the cars on the lot. One night while watching t.v., Jay encounters a preacher on television with a message that hits Jay over the head, making him realize what a jerk and dishonest person he's been. Jay repents, and turns his life over to the Lord. God then begins to work out the problems in Jay's life. It is truly inspiring to watch.
