In the grip of delusion, Professor Luis Romero (Luis Luque) assaulted a colleague he believed was stealing his research and might well have done the same to his wife Beatriz (Maria Abadi) if he had been able to get to her. Well, as Norman Bates once said, we all go a little mad sometimes. After spending some time in an institution, the Professor is pronounced cured, or at least close enough to be let back out into society provided he takes his medication. The one troubling factor in all this is that brain scans of Luis show no abnormalities, meaning the seemingly aberrant behavior he exhibited falls within the “normal” parameters of what he's capable of. This clever suspense film from Aregentina will keep you guessing right up to the end.
