Hidden

Four teenage friends - Sofi, Luna, Agus and Manu - agree to meet at a cinema.
When Sofi and Agus arrive at the address indicated by the cell phone map, they find an old house that is nothing like a movie theater. They knock on the door - just in case that had been a movie theater - but nobody answers; the door, however, is open, so they enter.
A quick glance at the place makes them see that it is not an ordinary house: the doors follow each other endlessly, the hallways appear in unthinkable places, each room hides a secret, the street door does not lead to the street...
Finally they convince themselves that in that strange place they have nothing to do and decide to leave, but when they are about to leave, Agus sees Luna's cell phone on the floor and they change their mind.
From that moment on, a search will begin - first Sofi and Agus, and then also with Manu, who they meet inside, confused, going from room to room - trying to find Luna.
In that search, Sofi, Agus and Manu will cross thresholds to move to unique places - a forest, a hidden room, a stream, an open field - where they will gradually discover clues related to the four elements of nature - water, fire, air , earth - that will help you finally find Luna.
