Sofía finds a mysterious box in what’s going to be her new bedroom — inside, a bunch of old cassette tapes stacked up. Each one’s labeled with a name, a time, and a place in the house. When she plays them, she realizes they’re recordings of spirit sessions done there thirty years ago. Curious to find out if her new home is actually haunted, Sofía calls up her best friends, Camila and Verónica, for an unforgettable girls’ night.
