Aksel returns to his hometown of Lifjord after 20 years to save the area's cornerstone company Solar Tech, which is on the verge of bankruptcy. But his return reminds people about an unsolved murder.
More and more people in the small town are starting to see the value of keeping Solar Tech alive rather than holding a grudge against Aksel. The Hansteens are divided about whether to sell the firm.
Aksel must stay in Lifjord and looks for a new CEO for Solar Tech when Eva decides to leave the company. Conflict arises in the Hansteen family as a result, and Lars's loyalty to his mother is tested.
Aksel's wife Angeline and son Tim arrive in Lifjord. Eva gets her hands on some old case files. She is determined to find something the police overlooked that could reopen the case against Aksel.
Angeline no longer believes in Aksel's innocence and he needs Tonje's help to prove he's not guilty. William wants to take on a new project and looks at the possibility of investing in the hotel.
Cutbacks at Solar Tech mean Lars has to start firing his friends. Aksel attempts to solve the mystery of who Karine's murderer is, but the more he digs, the more his innocence comes into question.
Aksel's suspicions about Per Olav increase when he finds out that he is beating his girlfriend Ase. William and Inger's plans to expand the hotel gain fresh momentum now that Eva is on board.
Aksel finds out that more people have been lying to him about the night of the murder. Eva and Inspector Kristoffersen proceed with the DNA test. Frustration builds up among the townspeople.
The police are looking for Aksel's bloody t-shirt from 20 years back, but he can't remember anything about the night Karine was killed. Eva's behaviour causes frustration and concern for her family.
Aksel must choose between his two lives. After an unexpected confession and surprising DNA test result, the police are sure they have found the true killer, but Eva thinks something isn't quite right.
