Bersærk is a mockumentary following Archie, a young British-Chinese immigrant, who lives in Denmark and believes himself to be the reincarnation of Thor. Through handheld footage and talking heads, we see how his state of mind has affected him in his day-to-day life. Archie is now not only subject to verbal abuse because of his ethnicity, but also because of his newfound belief. This reinforces society's exclusion of him, to the point where he places all his frustrations on his ex-girlfriend, Jette, whom he believes to be a jætte troll plotting Ragnarok. She files a restraining order against him, which forces Archie to recognise his delusion. The film crew reaches out to Jette in search of an ending - only to discover that she was a troll all along.
