The body of a teenager is found, emptied of blood, the murder rumored to be part of a ritual killing. Twelve-year-old Oskar is personally hoping that revenge has come at long last - revenge for the bullying he endures at school, day after day. Eli is the young girl who has just moved in next door. She doesn't go to school and never leaves the house by day. Sensing in each other a kindred spirit, the two become devoted friends. What Oskar doesn't know is that Eli has been a teenager for a very…very long time.
