The Door

When a gang of thugs steals a door to another world they use it to create a highly addictive substance who's effects are as alien as the place it comes from. Demand is high, acquisition dangerous and every trip through The Door is starting to have a larger and larger impact on the unsuspecting world around it. And if that isn't bad enough, the police are on their trail, there are monsters that chase them, and now something might be following them back into our world.
