Taylor Dixon knew having his little sister, Marissa, at camp would be a pain. He never imagined the pain would go so deep. At 15, Taylor wants nothing more than to get his drivers license. But Dad says he must prove he's responsible by staying out of trouble. Marissa's adventurous spirit is what usually lands him in trouble, but she's the only one who believes in his dreams. Taylor returns to Rustic Knoll Bible Camp expecting the usual sermons, softball and swimming. Instead, he discovers a vintage Mustang in the camp's machine shed, and the owner's invitation to help restore it fuels his dream of becoming a race car driver. But Marissa falls for Taylor's snobbish cabin mate, and her thirst for excitement pulls Taylor into a rivalry of words and deeds that threatens to destroy not only Taylor's hopes of getting his license, but also his dreams for the future.

Can Taylor keep a lid on Marissa's antics? And will the message hidden in the old car's engine change his attitude before it's too late?.
