James (James Allen McCune)'s sister has been missing for 20 years, and she is the protagonist of the legend of the Blair Witch of the Black Forest, which once made a lot of noise. James has always believed that his sister still lives in a corner of the Black Forest. One day, James saw a strange video on the Internet, and the person who recorded the video was his sister. In order to find the whereabouts of his sister, James and his friends Pete (Brandon Scott), Lisa (Callie Hernandez) and Ashley (Corbin Reid) decided to revisit the old place. James found the brother and sister who uploaded the video, and under their guidance, the group gradually went deep into the Black Forest. The beautiful scenery of the Black Forest made Pete and Ashley relax their vigilance, but after nightfall, the successive strange noises and the witch totems that appeared without reason made them panic. James thought that the brother and sister were behind this, so he drove them away, but the situation did not get better after they left.
