In this film based on a true story, Jack Black plays Jan
Lewan, a striving and struggling shyster who builds a polka music empire by
swindling, cheating, lying and conniving his way up a social ladder to create
the world's only "polka Ponzi scheme." Jenny Slate stars as Lewan's
adoring wife, while Jason Schwartzman plays his friend and sidekick. What could
be better than a Polka crime dramedy?
