A little boy disappears without a trace from a kindergarten in Stockholm. Police inspector Mina Dabiri and her colleagues quickly discover a similarity between the circumstances of this disappearance and another, earlier child abduction. That incident ended very badly. But... there are no connections between these two children and their families. Then another kidnapping occurs - following the same pattern. And again, not a single trace...
Desperate, Mina turns to the famous mentalist Vincent Walder, who recently assisted her with a very difficult and dangerous case. It turns out that if the city is imagined as a chessboard, the abductions occur according to the well-known chess puzzle "The Knight's Move." And if the mad chess player is not stopped, even more children will be abducted and killed...
