Ten Americans with a strong longing for their Swedish roots come to Sweden. The very first walk offers an emotional discovery when Guy Clark stumbles upon his own Swedish history.
The Americans get to get to know Swedish camping culture. Greg gets a clue to his unknown Swedish family and stumbles upon a lifetime's living link to the past.
Eric, whose ancestor was a bodyguard for the then king, gets some important pieces of the puzzle in place. Americans also learn that Sweden is not only an Astrid Lindgren country, there is a darker side as well.
The Americans are out on Birka where they get to live and live like the Vikings did. So they drink "mjöd'" and eat roasted lamb. And Jessica learns about her family's past, which turns out to have a strong link to her own life choices.
The Americans' dream summer in Sweden is coming to an end and it's time for the finale. Ten participants have become four and in Kiruna and Jukkasjärvi it will now be decided who stands as the sole winner.
