Detective Peter Wendel’s plan to set up an outstanding cold case team encounters a set-back when an unknown killer leaves a message for the police stating that Sweden’s most notorious serial killer is actually a fraud.

In order to uncover the truth, Peter has to pull his cold case group together quickly but is limited to the misfits of the police force who are the only officers currently available in Stockholm. From the outset his newly formed team find themselves at odds with the powerful group of people who had the serial killer convicted in the first place.
