A UFO crashes into the earth’s atmosphere in a forest near a small town. Inside is Sky, a young, adventurous alien from a planet 13 light-years away. While waiting to be rescued, Sky hides by transforming into the body of Millie – the entitled and snobby prom queen and the most popular girl in high school. With only three goofy friends to help her out, Sky must survive two weeks on Earth without being discovered. Sky is a classic coming of age show, depicting the drama of adolescence through the eyes of outsiders who feel, each in their own way, a little bit like aliens themselves.
