Willie Brown's Nifty Nine have a big game on an afternoon that Willie is tossed in jail for making sport of a cop. With their star behind bars, the Nifty Nine quickly fall behind the Tar Heels, a Black team, at the Polo Grounds before a packed crowd. It's up to Felix to save the day. But first, he has to get to the park, then he needs an idea. In this mix of animation and live footage of cars, trains, and baseball fans, Felix needs an assist from Jupiter Pluvius.
