Viola becomes furious when she learns that her high school, Cornwall, has just cut the girl's soccer team. So furious, in fact, that she takes advantage of her twin brother Sebastian skipping town for a few weeks to take his place at his school, Illyria, so she can join the soccer team there. But her disguise as her brother leads to major complications when she falls in love with her soccer-playing roommate and the girl he's in love with falls in love with "Sebastian".
