In 2012 the young entrepreneur Jonah Colomes from Barcelona disappeared from Baserca forests without a trace. Fifteen days later the police closes the case citing a voluntary disappearance, not finding any clue on the young. Family members did not believe the version and when they tried to find information on the media, it is uncovered that Jonah had defrauded the Treasury and was about to be charged in a plot of money, which gave more consistency to the hypothesis of the authorities. Two years later, the actress and journalist Marta Romero meets Jonah Colomes' sister and is ready to make a documentary recounting the facts and inconsistencies. Before climbing the Baserca's mountain (a lush valley filled with forests and isolated due to the construction of a dam)she receives a phone call from a woman who found a cell phone, Jonah's phone, and through his contacts have been able to locate the relatives. Jonah's sister insists on bringing the phone to the police, hoping to be able to reopen the case and to prove that his brother had not disappeared. But when it comes to the police station, the police says that the phone is empty, there is nothing. A version that contrasts with the family who found the phone, which ensures that before giving it to the agents, there were material. The son of this family, gets into the content and discovers that someone has done a hard reset the phone. The photographs show that before disappearing Jonah had had contact with a congregation fanatic, a Christian camp and a mysterious figure of a person. Legend has it that in 1968 the Mayor's granddaughter had disappeared and given up for dead, but the body was only seen by the grandfather and the police. People believe that the girl was alive during that time and that something has gone dark. Others dare to say that she was forced to participate in satanic rituals and that Jonah and the other disappearances could be related. But who is the dark hand that does not want to encover this? Are Jonah or Enrica still alive?
