The group goes into the forest to celebrate the life of Ana's sister Eva, who disappeared there two years ago along with three friends. While camping near Eva's favorite oak tree, Matt tells a local legend about an asylum patient who was burned alive in the forest after murdering her family and tormenting others with an strange book. Ana becomes worried that the legend may be connected to Eva's disappearance. Later, the group decides to explore the ruins of the old asylum mentioned in the story.
