Psychiatric patient Elmeri knows about the existence of a gold treasure in Finnish Lapland, hidden there by his late father who somehow managed to capture it from withdrawing German troops on the last days of WW2. His openly gay nurse helps him escape from the mental institution, and the two men slowly find their way up north to reach the gold. On their way, the odd couple meets a cavalcade of even odder characters.
