Howl

Joe, a young ticket-collector, circulates outside London in the last train of the day. It's a dark and stormy night, and the vehicle is accompanied by a meager group of passengers. At one point, the train stops abruptly, apparently because it has hit against something emerged from the forest. The driver leaves his cabin to investigate. And no returns. Passengers enter in a panic, especially after Joe divise the mutilated body of the driver.

With the certainty that something evil and bestial lurks outside, Joe decides to erect barricades to prevent them, whatever it is out there, among the car. The creature (a huge wolf) gets in, and the group confronts it getting him to death. But then, a series of howls predict what will be coming.
