In Buenos Aires, laborer Jose Maria and mansion servant Rosa meet and fall in love. However, they conceal their romance from her censorious employers Senor and Senora Blinder. When his foreman Dali calls him names, Jose confronts his boss and is fired he feels unjustly as his superior started the incident. In a rage, Jose kills Dali violently.
The police seek Jose who tells his beloved Rosa he must leave the city. However, instead of going far away from Buenos Aires, Jose hides inside the huge mansion in an empty area. He watches the owners and their son Alvaro to insure they treat his beloved appropriately while clandestinely stealing food. When Alvaro rapes Rosa, Jose in a rage kills him.
This is an odd but exhilarating thriller that sort of feels like taking Hitchcock's Rear Window and relocating it in Argentina. The violent hero is for the most part like a ghost or the comic book Watcher as he keenly observes the goings on inside his small world (self-prison) mansion. This is Jose's tale as his raging mind enables readers to ironically "view" the darker side of society.
