Det som göms i snö 2018

After a long sick leave and recovery police detective Peter Wendel is back on duty. He is commissioned to form a new team to reopen unresolved murder cases, however he soon finds himself with a rather third rank and conflicting staff. Soon they are in the center of a new case. An unknown murderer claims that Sweden's most infamous murderer is a fraud - that he never committed the murders he's jailed for. High reaching implications are to be exposed, involving even the Swedish government.
