Shelby is on a weekend wilderness retreat with Cindi, Noah and some strangers when she hears about a micro-chip stolen from a computer lab on the radio. According to the report, the dangerous thief passed through the same bus station where Shelby and her friends had been just that morning. It’s not until they’re stuck in a cave with the other campers that they realize someone planted the micro-chip on them. And that means that someone else in the cave is probably the desperate thief!
