In the seaside Danish town of Elsinore, the personal and professional converge for DCI Dan Sommerdahl; his estranged wife, criminal technician Marianne; and his best pal and partner, Detective Flemming Torp. Separated after 25 years of marriage, Dan now asks for a divorce despite still being in love with Marianne. She, meanwhile, wants to rediscover herself which gets complicated when Flemming, needing a place to stay and harboring a torch for Marianne, moves in with her. As they contend with these romantic entanglements, the trio continues to investigate murders together, including the killing of a famous musician, a chef's assistant dead in a restaurant fire, a paralyzed patient's demise at a nursing home, and the possible connection between a schoolteacher's death and someone at the police station.
