We've all been there - the dreaded early morning commute. The surly driver; the obnoxious teenagers; the guy who just has to invade your personal space; the awkwardness as everyone avoids any kind of social interaction with anyone else; the frustrations of snarled-up traffic and tail-backs. For most of us, the trip on public transport is about as bad as it gets. For these passengers, it's about to get a lot worse. Jonathon, Justine and Hanna don't know each other but they're about to be thrown together as a simple journey to work turns into a race for survival when a mysterious object falls from the sky, initiating an alien invasion. Mutated monsters, trigger-happy soldiers and personality clashes abound on: The Last Bus.
