Crazy Old Lady

One stormy evening, Pedro answers a desperate call from his ex-girlfriend, Laura. He agrees to spend the night looking after her senile mother, Alicia, whose nurse has mysteriously vanished. But the moment he steps inside the house, Pedro feels something is very wrong: Alicia doesn't seem to recognize him, and he realizes that she actually mistakes him for Cesar, a secret past lover with whom she shared terrible secrets. As night draws on, Pedro is held captive in the house by Alicia, who displays an increasingly twisted determination to make him - or rather Cesar - pay for the pain she endured in her tormented past.
