A couple of average guys from Milwaukee, Joe Cooper (Trey Parker) and Doug Remer (Matt Stone), become disillusioned with the state of sports today. Instead of watching sports, they begin to play a game in their driveway. The game becomes known as BASEketball, and it catches on very quickly because anyone can play it. With the funding of billionaire Ten Denslow (Ernest Borgnine) and their third team member and friend Kenny “Squeak” Scolari (Dian Bachar), Joe and Doug found the professional sport of BASEketball. Unlike other professional sports in BASEketball everyone player gets paid the same amount and no team can change the city for which it plays. As they become national sports heroes they are faced with the problems of corporate sponsorship and corruption that turned them away from league sports initially, they try to fight back. When the owner of a rival team, Baxter Cain (Robert Vaughn), decides to take matters into his own hands and try to change BASEketball’s cardinal rules, the only people that stand in his way are Joe, Doug, and Kenny.
