In 1974 two men vanished several months apart. Iceland, with a population of just over 200,000, was a close, tight-knit community where everyone knew everyone, but the police got nowhere: there were no bodies, no witnesses and no forensic evidence. Then six suspects were arrested and confessed to the murders, many facing long, harsh sentences. It seemed like justice had been done, but nothing could be further from the truth. Forty years later, this notorious murder case was reopened when new evidence brought into question everything that had gone before. It became clear that the suspects had very quickly lost trust in their memories and were confused about their involvement in the crimes they had confessed to. The extreme police interrogation techniques were brought under intense scrutiny.
