Duncan discovers a small girls bicycle in the garage of the beach house and uses it to begin exploring the town. At a pizza restaurant, he runs into the staff of Water Wizz, the local water park. He meets Owen who is playing PacMan, and eventually Owen takes Duncan under his wing and shows him around the park. Duncan meets the parks colorful, ragtag group of employees Caitlin, Lewis, and Roddy. Several kids at the water park speak reverently of a legendary pass in the tube slide, wondering how it could have been done. Owen hires Duncan for odd jobs at the Water Wizz.Outside the park, Duncan is continually neglected by his mother, Pam, who indulges in drinking, staying out at night, and smoking marijuana with other adult vacationers. At a Fourth of July cookout, Susanna sees that he is upset about this and invites him to go hunting for ghostcrabs with her and Peter, where she talks about her absent father and helps Duncan to open up. Later that night, Duncan witnesses Trent and Joan kissing by the side of the house, but does not reveal what he saw. ........
