Three Doberman dogs are holding a group of young people inside the swimming pool of a luxury villa they have snuck into in Mallorca. Time is running out: one of the boys is injured with severe bites. Despite his screams, no one comes to his aid: all the local residents are at the traditional paella to celebrate the start of summer at a nearby estate. Those attending this party suffer a strange spell that prevents them from going into the pool, as those who bathe feel the pain of the young people from the other estate. It is the eve of Midsummer's Eve, a day of magic.
