From the liner notes

When Jules (Cameron Goodman) and Mel (Peyton List) return from a girls’ weekend vacation, they find themselves stranded at the airport, late on a rain-drenched night. Wanting just to get home safe and sound, they board an airport shuttle with a helpful, friendly driver (Tony Curran) for the short trip...that turns out to be anything but safe. From writer-director Edward Anderson, making his directorial debut, comes a terrifying thriller about a night that starts like any other, and a ride home that descends into darkness.
