With no other options, the Waldemar siblings have been forced to work with arch-rivals Rosén, but can they be trusted? The night after Kim's bachelor party, an accident occurs.

Kim and Cecilia are shaken by the accident, and the sale of the hotel is in danger, something that Mikael Rosén uses to his advantage. Liv has a secret that will affect everyone.

Oskar approaches Marja in the hope that she can help with the sale of the hotel. Mikael stands up for the pregnant Jonna. Meanwhile, Kim confides in Lasse.

Lasse babysits Max and discovers new sides of himself. Liv is desperate and tells Mikael about the cancer. Jonna makes a decision, and Flemming finds clues about Georg's disappearance.

Rönn realizes that things didn't go quite right with the arena construction. Lasse tells Tom about Mikael's business, and the Rosén brothers meet in a fight where the past comes to the surface.

It seems that everything went right for the Waldemar siblings, but Flemming is determined to defeat them once and for all. He finds some final evidence to use against Kim and Cecilia.
