David Weiser is found hanged in the forest. He had once transformed himself from a former start-up entrepreneur for superfoods to a radical dropout. His brother Timo, co-founder of the company, took care of his brother and tried to persuade him to return again and again. As the SOKO team finds out, David suffered from depression after he was involved in an accident in which the Youtuber Silvie Regensburg was seriously injured. In addition, Weiser's drug past comes to light, and the homeless Raimund Frank, who also lives in the forest, is picked up.
