The owner of a huge house in the woods, in the town of Barrancas, has a reputation for not paying his employees. When the latest housekeeper goes missing, everyone simply assumes that yet another employee has quit. Meanwhile, back in the city, the owner’s nephew Mario is tasked with going to Barrancas to hand over the keys to the new caretaker. Young Mario thinks it’s a good idea to secretly invite his friends from college, as well as the girl he likes, out to the country house for a fun weekend. What Mario doesn’t know is that this may turn out to be a very dangerous idea indeed.
