In this Swedish horror film, a bullied 12-year-old boy named Oskar develops a friendship with his moody new neighbour Eli, who appears to be a young girl around his age. As it turns out, Eli is trans (as well as a vampire), but Oskar is unfazed by all this, and the two develop a sweet relationship — until Eli confesses to the horrible string of murders that recently occurred in their town.
