"EL ARBOL" José is a homeless person who spends his nights collecting PET plastic, to sell it and thus support his only daughter. One night you will find the true value of assembling the Christmas tree, as a family.

In the region, whose name is not advertised, murders, kidnappings and unexplained mystical events began to occur. The police find victims not only adults but also children, people disappear. At first glance, all these events seem completely unrelated, but the old police captain after another murder finds similarities with the cases of the past years. Those cases were investigated by his younger partner, whose daughter disappeared under unclear circumstances. The captain decides to involve his partner in the investigation of the events, but finds him in a deep depression close to suicidal schizophrenia. Together they begin an investigation that may lead them to a denouement, if they find the strength to go beyond the law and the ways of obtaining information, because some people who know about the puzzles of the whole picture-there is a price for a piece of the puzzle.
