As the restaurant’s about to close for the season, Calle and Sonja's marriage is cracking at the seams, while Nina sinks into depression, despite Helga and Backe’s help.

Nina visits Erik and Christina in Skåne, but it’s not a harmonious reunion. Helga suspects that something happened between Nina and Calle on Midsummer's Eve.

Peter and the other staff prepare the midsummer celebration at the summer restaurant. Nina and Calle are colleagues but, beneath the surface, deeper feelings burn.

As the Löwander family is preparing to open their restaurant, Nina meets Calle again for the first time since she tried to take her own life.
