After his father's recent death, Zach Cooper and his mother Gale move from New York City to the peaceful town of Madison, Delaware. While settling in the neighborhood, Zach meets his neighbor Hannah, but her overprotective father warns him to avoid contact with them. The next morning, at Madison High School, where Gale works as vice-principal, Zach befriends Champ, a clumsy student. That night, Hannah invites Zach to an abandoned amusement park where they start to befriend. However, when they return home, Hannah's father warns again that Zach stay away or something bad will happen.
