After two Eastern European corpses are washed ashore on a raft in Ystad (they've been shot through the head and had their tongues burnt off with acid), Wallander travels to Latvia on the hunt for the killers. Thrown into a cold, alien world of police surveillance and lies, Wallander soon finds himself entangled in a web of corruption with no-one to trust. An anonymous phone call, a shooting and a break-in at the police HQ soon convince Wallander of a leak in the investigation - and he immediately suspects Liepa. Guest starring Soren Malling (that's only Jan Meyer off The Killing), with Kenneth Branagh as the world-weary detective.
