Dumb Jock is a touching, coming-of-age story about a reserved, self-conscious, teenage boy growing up in a small northern-Michigan town. Jeff Irwin is short for his age, timid and studious, never yet having dared to take any chances for fear of ultimate rejection or failure. He is a bit of a social outcast and lives quietly in the shadows of the popular kids at his school.

Afforded the opportunity to assist the town's high school football hero Brett Willson, Jeff embarks upon the challenge of educating the world's dumbest jock. The ensuing relationship that develops between the two young men proves far more challenging, however, than any tutoring session. Their budding friendship helps bring Jeff out of his shell and reveals a much deeper side of the dumb jock.

Tragedies befall the ill-suited young couple, and the losses they endure are unthinkable. In the end, however, they must decide whether to be true to their identities or return to the previously held conformity of their comfortable stereotypes.
