Two losers, desperate to pay off a mobster, host a dance at the local arena - but forget to specify.  As they fall out, the girlfriends and locals take over as mariachis, Chinese ribbon dancers, cowboys and cowgirls, African dance troupes and others audition.  As the guys return from fighting with their families, still not talking, they shove dancers on stage in a cataclysmic mish-mash - as the mob robs the box office!  Can dumb luck and good intentions save the show and set the whole city dancing?
