Three friends are staying at one of their homes. At first, the weekend seems completely normal, but Sofía tells the legend of a man named Vicente, who was murdered in cold blood inside that very apartment. She says that if you say his name three times in front of a mirror, he will return to take revenge on anyone who dares to disturb his rest. The young people see it as nothing more than a bit of fun and an old legend.

Sisters Miriam and Sandra, accompanied by John, the latter's boyfriend, travel along secondary roads to see the old mansion that their late grandfather has left them in his will.
