Lisa Forsberg is a rookie cop who has just taken her first assignment in the small Swedish city where she was born. In her youth she was a troublemaker, part of a hard-living subculture called "raggare" who worship American rock'n'roll and vintage cars from the 1950s. Now Lisa finds herself thrown back into this world when she is sent to investigate a missing person report involving people she went to school with. She and her partner, Erik Lund, will uncover secrets that put them in harm's way and bring them face-to-face with the unspeakable.
