To escape his haunted village, Arjun breaks a generations-old taboo and boards a train with his father. But this is no ordinary train. It is a living, breathing predator of steel and flesh, and the price of a ticket is far more than money. Trapped in a carriage that digests its passengers, Arjun discovers the horrifying pact that binds his village to the monstrous engine, a deal that is about to expire. The ride has just begun, and the final destination is damnation.
