In 1924 Boston, Private investigator and war veteran Edward Pierce suffers from increasingly bizarre nightmares, and self-medicates with sleeping pills and alcohol. He is soon contacted to look into the case of the Hawkins family, who mysteriously died in a fire. As the only clue is a strange picture painted by the supposedly crazy mother shortly before her death, Edward has to set out to Darkwater Island off the coast to find out more about the matter.
