Cody, Feather, Jeremiah, and Larry have other reasons for calling their 3-on-3 summer basketball league team "The Lewis and Clark Squad." But considering the crazy situations they get into, they might as well have named themselves after the famous adventurers from their history books. In their first adventure, mysterious weird objects keep appearing in an abandoned out-of-state pickup on a neighbor's property. Yet the kids never see anyone around it. It makes no sense until they find their first clue: a roll of film. There's only one way to solve the mystery. They decide to spend a night watching the truck. It's an event they'll never forget!
