They're not just a summer basketball squad--they're a lean, clean, adventure-finding team!

Cody, Feather, Jeremiah, and Larry have other reasons for calling their 3-on-3 summer basketball league team "The Lewis & Clark Squad." But considering the crazy things they're going to get into, they might as well have named themselves after the famous adventurers from their history books!

Their first adventure revolves around an abandoned out-of-state pickup truck on a neighbor's property. From day to day, someone keeps moving weird objects from inside the locked cab to the truckbed. Yet the kids never see anyone out there!

It makes no sense until they find their first clue: a revealing roll of film. But even with that, what's happening is a mystery. In their minds, there's only one way to solve it: spend a night watching the truck.

What will they find come morning? Something they never imagined--and something they'll never forget!
