S02E31 - Face the Midnight Sun and Fire
Synopsis
The sun doesn't set during summer in Stockholm. There, two beautiful twins, Latica and Anita, are fighting a repeated deathmatch. The reason is the location of the Viking treasure which is concealed on their backs. Lupin, playing two different roles, manages to photograph the map on both their backs, which only appears during the Summer Solstice, but the map has an additional secret!
