Today is the biggest day in the super-organized life of uptight overachiever Jane Ryan (Ashley Olsen
). She's due to give a major speech for a competition to win a prestigious scholarship to Oxford University. Meanwhile, her rebellious sister Roxy (Mary-Kate Olsen
) is planning to ditch school and go backstage at a music video shoot in Manhattan, where she'll slip her demo tape to the band's A&R team.
Despite having little in common, the sisters reluctantly journey together to the Big Apple, but their plans go wildly awry when a mix-up involving Jane's all-important day planner lands them in the middle of a shady black market music piracy scheme. Sidetracked, sideswiped and hotly pursued from Chinatown to Harlem by a truancy officer (Eugene Levy) and a wannabe gangster (Andy Richter), Jane and Roxy join forces. If Jane doesn't recover her day planner and the speech inside it, she can kiss her scholarship goodbye. And if the truancy officer finally catches up with Roxy, she'll be drummed out of high school for good.
