The classically simple premise of Shuttle sounds like a horror movie, tapping into an uncommon fear you push back into the corner of your mind, marked "unlikely -- I hope." Best friends Mel (Peyton List) and Jules (Cameron Goodman) arrive at an airport late one rainy night, returning home from a trip to Mexico. Mel is feeling sick and unsteady on her feet, giving smooth-talking Seth (James Snyder) an opening to start flirting with the two young ladies, and forcing his traveling buddy Matt (Dave Power) to tag along.
The attractive foursome end up together on a shuttle mini-bus, along with a very nervous man in a business suit (Cullen Douglas). The driver (Tony Curran) takes an odd detour through a bad neighborhood; when questioned, he insists he knows where he's going. As the blocks of abandoned buildings roll by, the kids become agitated. The increasingly tense atmosphere on the shuttle is ratcheted up by a near-collision with a speeding car, and the driver's maneuvers to avoid a wreck result in a flat tire. Matt volunteers to help the driver change the tire, and that's when things really start going to hell for the shuttle's unlucky passengers.
