All his life, Joshua Carter, town hero, prom king, and captain of the baseball team. has been told of stories from his neighbor, Dutch(arnold!), whom he ready the paper to every week. Although he though it was just a bunch of stories he soon discovers its all true because his girlfriend was brutally murdered by an alien. Here he joins the fight and confused about what side to join , he kills both aliens, and shoots a pred with his dads shotgun.
however, he realizes that he is not the target for the predators and dies in an attempt to save a pred. who had saved his mother earlier.
