When wealthy doctor Ríkharður Magnússon goes to sleep in his luxurious caravan and doesn’t wake up, detectives Guðgeir Fransson and Elsa Guðrún are called to the Westman Islands to investigate what looks like murder.

Suspicion immediately falls on Ríkharður’s young, beautiful and deeply troubled girlfriend – but there are no easy answers in this case as they are drawn into family feuds, disgruntled friends and colleagues, and the presence of a group of fitness-obsessed over-achievers with secrets of their own.

As their investigation makes progress, Guðgeir and Elsa Guðrún are forced to confront their own preconceptions and prejudices as they uncover the sinister side of Ríkharður’s past.
