A businessman checks into a hotel and discovers he's trapped in a logic puzzle that only Gregory, the mysterious mouse owner, seems to understand. Every choice you make locks you deeper into the mystery instead of getting you out. The horror isn't in jump scares, it's in realizing this place operates on rules you'll never quite figure out, and the comedy comes from watching a grown man slowly accept that escape was never the point.

A businessman heading home from work by train ends up at Gregory House, a hotel for lost souls run by an old, sinister mouse named Gregory, who invites him to stay a while. Soon the man is caught up in a chain of bizarre events and tries desperately to escape this strange purgatory. The CG-animated short series tells 25 separate stories set in an alternate dimension, and each inhabitant of the hotel stands for a common, everyday fear. Every episode mixes comedy with horror, and the whole thing plays as a surreal, supernatural mystery.
