After stealing a jewel known as "La Piedra de Mor", the brothers Cosme and Saray Garza meet Koldo Ugartetxe, the gangster who commissioned them to do the job, in some lost cabins. The brothers will try to scam Koldo by giving him a perfect fake of the jewel. It seems that everything is going to be fine, until Koldo and his two henchmen arrive at the cabins and begin to suspect the brothers.

The popular influencer, Markel Allende, arrives at the cabins for a promotion. On a walk he discovers a living plant—a mandrake—that could relaunch his career. What could seem like a success is jeopardized when Markel introduces his "new friend" to his network. Markel runs the risk of being canceled by his audience and his biggest hater finding the perfect excuse to attack him in real life.

A band of geeks led by paranormal fan Sergio Berenbaum discovers that the clue to guide them to their first extraterrestrial contact could be found in some cabins near Mount Amboto. When they arrive they discover that the owners of the cabins are even geekier than themselves, and that Aliens are not the only paranormal thing lurking in the shadows of the forest.
