The plot: Polish-born Jan Lewan (Jack Black) is a polka
bandleader with quite the following in his home of Pennsylvania. In fact, his
fans believe in him so much that they are willing to invest thousands of
dollars into his numerous business, not the least of which being his music.
However, it seems that his business dealings aren’t entirely on the up-and-up,
as he soon finds himself under investigation for financial fraud. Will Jan have
to face his actions or will he go on to take the stage once again?
