All over Oslo, children are disappearing.

One afternoon after school, nine-year-old Emilie doesn't come home. After a frantic search, her father finds her backpack in a deserted alley. A week later, a five-year-old boy goes missing. And then another.

Meanwhile, Johanne Vik, a former FBI profiler, is buried in crimes of the past, trying to get to the heart of a decades-old false murder conviction that's been keeping her up at night. But Police Commissioner Adam Stubo, who's haunted by his own demons, sees her as his only chance at unlocking this deadly pattern. Johanne resists at first, but when the bodies of the missing children start appearing in their family's homes with notes that say, "You got what you deserved," she decides to help.

While the Norwegian media is out hunting pedophiles, Stubo and Vik feel that the truth may be a larger, more complex story of revenge, one they're desperate to uncover before time runs out. A singularly clever crime story combined with a serious discussion of children and our responsibilities towards them, What is Mine introduces one of the most original crime-solving teams ever.
