Saga and her new partner Henrik follow leads in finding their kidnapped boss Hans. In the meantime personal developments in Saga's life influence her work as a police officer.

A sceptical Henrik and Saga are initially unimpressed when a young art curator suggests a connection between the murders of Helle Anker and Lars-Ove Abrahamsson and the brutal attack on Hans, but his theory leads them to interview Freddie Holst, a successful businessman with a substantial art collection. The detectives are called to yet another victim whose mutilation seems to be the work of their serial killer.

Burglars make the gruesome discovery of two new victims, which Henrik recognises reflect the title of another of Freddie Holst's artworks called Cancel Christmas. The victims were foster carers and, whilst the team await a list of their charges, Saga and Henrik receive a breakthrough lead from John's new girlfriend Tina, who has been staking out the Holst house.
