In a Glass Cage

In a Glass Cage (Tras el cristal, 1986) is Agustí Villaronga's Spanish psychological horror you can watch online on iFILM.

Klaus, a former Nazi doctor, lies paralyzed in an iron lung after a suicide attempt. A quiet young man named Ángelo turns up at the house and offers to nurse him. It soon becomes clear that Ángelo knows everything about Klaus's crimes — and hasn't come to help. One sealed house, an old journal of atrocities, and the roles of torturer and victim sliding into each other.

Villaronga's debut remains one of the hardest watches in 1980s European cinema: cold, merciless, staged like a claustrophobic chamber piece. It isn't a horror ride but a slow study of how cruelty gets handed down. Not for the faint of heart. Stream In a Glass Cage (1986) online on iFILM.
