Vieja loca

One stormy night, Laura is driving down the highway and has a bizarre phone conversation with Alicia, her mother. Anxious about her mother's reaction and unable to get in touch with her caretaker, Laura calls her ex-boyfriend for help, asking him to look after her senile mother for the night. But what seems like a simple task soon turns into his worst nightmare: when Pedro arrives at the house, Alicia suggests they play an extremely sadistic game.
