Dude Schmitz, an independent filmmaker, attempting to secure funds for his second feature, blows an opportunity at what promises to be a lucrative interview with pop sensation Britney Spears.

Schmitz takes off for New Orleans with Stephens, promising him a chance to meet his teen idol, all the while taking film of Stephens' cross-country exploits and pawning them off as footage of the real deal.
