Season 1

Siblings Sara and Frank (now a police officer and a lawyer) as children watched their parents die in a car explosion. Sara is still pursuing leads to find out who killed their parents, and Frank reluctantly joins her investigations.

Frank gets a case at the law firm representing Thomas Waldman. He is given a week to win and for the first time is forced to play the game in order to get closer to the truth about his parents' death.

To win Waldman's confidence, Frank defends one of his henchmen. But things become complicated when the prosecutor turns out to be Patricia Staaf, with whom Frank had an affair and still has feelings.

Brian reveals to Frank that he has evidence that links the drugs business directly to Waldman, and Patricia agrees to give Brian witness protection. Sara is in danger of losing Liam's confidence by trying to help Frank.

Frank wants to avenge Patricia's shooting so decides against Sara's will to try to get Waldman's greatest enemy, Daniella Ayala, out of prison to create a drugs war. As a result, a gulf opens up between the two siblings.

Frank secretly helps his former colleague Fredrika to prepare for Daniella Ayala's review. Waldman becomes increasingly nervous and orders an attack against Ayala.

Sara is finally close to raiding the workshop in hope of finding drugs and putting away Bogdan. But when her team moves in there are no drugs to be found.

Sara gets fired from the police after her relapse and becomes increasingly indiscreet in her addiction. Frank tries to protect his sister whilst exploring every option to set Terese free.

Sara chooses to believe Blanka and decides to let go of revenge. Meanwhile, Frank is fighting in court to free an increasingly fragile Therese.

Sara's identity is revealed, and when Frank is ordered by Waldman to accompany him on a business trip to Lithuania, the siblings realize that they are running out of time.
