Beautifully shot by Håvard Byrkjeland, at a house in Oslo designed and built by architect Arne Korsmo (1900-1968), it begins dreamily but then develops a darker edge as the reality of this modern-day Hansel & Gretel's situation kicks in.

"The idea was inspired by a local news story," Kristoffer explains. "A mother left her young kids in the house and was gone for weeks. This happened in January, when I was writing the idea. I mixed that up with my own childhood, and a hint of something sinister."
