The inmates of an insane asylum take over the institution, imprison the doctors and staff, and then put into play their own ideas of how the place should be run.

This hidden gem from Juan López Moctezuma, an overlooked director who also co-produced El Topo, is one of the weirder Edgar Allan Poe adaptations. The unsettling mood slowly grows into what can only be described as sumptuous carnage, as the film finds a strange beauty in its characters’ madness.
