Who Do You Think You Are? (2008) : 8x6

Shane Jacobson's father, Ron, was born into a family of carnival workers and lived in a tent until he was 21. They know nothing of their ancestry, but Shane's convinced they come from Viking stock. His crusade will take him to Finland where Shane's great grandfather took drastic steps that echo down the Jacobson line. His journey will take Shane to a medieval church where his ancestor was forced to sit on a shaming stool to atone for her sexual crimes. His search for the truth behind his Viking roots is answered, and in a farmhouse Shane finds his extended Finnish family.
