Dillon is in training – one day he hopes to run, swim, bike, and win the Ironman triathlon. But before he can do that, he must deal with his brother Preston’s recent suicide and the role he played in it. Dillon runs to lose himself, to forget about his family falling apart; to sort out his feelings for Stacy, Preston’s girlfriend; and to stop thinking about the secret that his friend Jennifer has just entrusted to him – a secret about herself and her step-father, T.B. Dillon can’t keep running from these problems and he knows it. With the help of Jennifer’s basketball coach and his father, Dillon learns to accept his problems and take responsibility for the only thing he can control – himself.
