Together with her team, Detective Lois deals with the most serious type of crime: murders, kidnappings and other extreme violence are her daily reality. However, Lois has been used to her fierce profession for years; she lives more or less for police work. After the early loss of both her parents, Lois' sole trusted person, her sister Tessa, who recently married the rich Guido and moved to Bergen. For the rest of the outside world, Lois has no room: she has created a controlled, safe life for herself and keeps to her self-imposed 'rules' at all times. However, if a secret from Lois' past suddenly comes to the surface, that quiet life will be turned upside down. Lois' very private life comes to the fore against the background of three heavy affairs. Not only does she threaten to lose her only true ally, but the roller-coaster also has the necessary effect on her work as a detective. Everything that Lois has always taken for granted, will come to a standstill and she will have to change something for the first time to keep her grip on her life.
