During the bright Nordic summer, a group of children reveal their dark and mysterious powers when the adults aren’t looking.

In this original and gripping supernatural thriller, playtime takes a dangerous turn. 7-year-old Norwegian Ida must make new friends when she moves with her autistic sister Anna and her parents to an apartment complex on the outskirts of Oslo. While her parents are unpacking things and busy with work, Ida explores the area and, to her annoyance, has to babysit Anna, who cannot talk. Soon Ida meets the two years older Ben and Anna finds a buddy in the gentle Aisha. They live in the same complex as the sisters and appear to have special powers. More and more often Ida and Anna go outside to play with their new friends, but their initially innocent game gradually takes a grimmer turn.
