The normally so closely united family is having a crisis. Mie and Ole can no longer stand sharing a room, big sister Sis is tired of acting as the family's spare mother, and Father does not have the usual surplus to tackle Uncle Anders' peculiar behavior. Leaving Tiny Per, alone and sad about it all. Uncle Anders therefore enrolls the family to stay at a family therapy center, where they must live as Vikings for a week

Everyone is afraid of something. Also Father. He suffers from a terrible case of fear of heights. And for him to not decline a new job opportunity, located on the 27th floor, which could save the family from moving across the country, the family decides to travel to Norway to cure his phobia. But it will soon be clear that Father's phobia isn't the only obstacle standing in their way.

The kids and Uncle Anders want to participate in the hotels competition to become “The Sunny Family of The Year” but father says no, underlining that “We’re good enough as we are!” He changes his mind, though, when he meets the competing family, and recognize the father as his old school mate, who’s been bullying him for all of their school years, for being physically inadequate. Consequently father enters the competition with all his might and heart, and what should have been a friendly contest, ends up being a fight for honor and redemption, and it’s only by the loving and innovative intervention from the kids, that father in the ends realizes that the family really doesn’t need to go to any of such extremes. They are actually good enough as they are!
