María has returned to the house where she grew up after twelve years without going. There she can get a lot of material for her new photography exhibition.

Everything is perfect until one night, a noise coming from the floor below catches Maria's attention. She feels that all the people of that village hide something, including Luis, her only friend and with whom she shares a small story of summer love.

Every day that passes everything is stranger and the noises coming from the floor below are stronger every night.
