A train breaks down in the countryside only a few miles from its departure point. The few passengers on board are getting restless as the train staff attempts to figure out what is going on when all of a sudden, a beat howls outside. The train becomes under siege by a beast who wants to snack on its passengers like canned food. The setting and premise here are simple: People in one location, being attacked, needing to escape. Co-written by Nick Ostler and Mark Huckerby, both of whom mostly have children tv show credits, the script works within its limited setting. They build the characters just enough which is to say, most characters are fairly basic, but they work as beast fodder that the viewer care enough about to have a reaction to their demise.
It also means that the last survivors are easy to spot as they are the most developed characters, which is fairly par for the course with horror movies like this one.
