Something strange has always happened in this city. People often disappear here, mysterious cars appear out of nowhere, and David and John also live here, quite ordinary guys who were once unlucky enough to accidentally open a door to another world (hell, dimension X, Xen, the metaverse - whatever people called it) . But if you see it, then the local inhabitants also see you, and they are very curious and often very hungry. And then something begins to happen in the city that no nightmare would ever dream of: shadow people, clones, slugs, tentacles, creatures that cannot be described in human language, and monsters. Lots of monsters. Both David and John quickly understand that some doors are very difficult to close, and the reality is much more interesting and scarier than it seems to humanity.
