Margo is struggling to deal with her son, Jon a rebellious and free-spirited teenager who runs with a bad crowd. After Jon is expelled from school, Margo sends him to live with his grandfather Max, a retired military officer who lives in a small coastal town and believes he can fix his grandson with his own style of discipline. This new home does not equal an attitude change, and when Jon is seriously injured after being involved in a grave crime, both boy and man will learn to face their fears and limitations.
