It's a beautiful fall day, and golden leaves skitter ahead of the wind across green lawns. Walking through the park on his way to class, Eli persuades a punk-rock couple to pose for some photographs. Nate finishes football practice and goes to meet his girlfriend Carrie for lunch. John leaves his dad's car keys in the school office for his brother to pick up. In the cafeteria, Brittany, Jordan and Nicole gossip and complain about their mothers' snooping. Michelle dashes to the library, while Eli snaps some photos of John in the hallway. John walks out onto the lawn, crossing paths with Alex and Eric. An ordinary high school day. Except that it's not.
