Izzie is restless, and eager to be treated like an adult. So she decides it's time to make some changes. But the new Izzie comes with new problems. First, there is Josh Harper, an older, cute but wild boy. Then there is her mother, who is opposed to every part of the "new Izzie". And then there is one night at Nesta's house, when Izzie decides to make cocktails . . . In the process, Izzie learns a great deal about herself and what it means to be grown up, but not before she's upset just about everyone along the way.
