Murder investigator Evert Bäckström is convinced that crimes have been committed when a women's cranium is found on an island in the archipelago. But his investigation is countered by the police chief and when the woman's identity is clarified, the entire investigation is turned upside down.

Bäckström goes to Thailand to dig for the truth about Jaidee's life and death. At the same time, the investigative team in Stockholm is following a completely different track. They are convinced that Jaidee died in the tsunami and soon Mimi's husband is arrested.
