When magical princess Star Butterfly receives a royal magic wand for her 14th birthday, she proves to her parents that she is not ready for the responsibility that comes with it. As a result, they send her to a place that doesn't have magic -- Earth -- in hopes that she will gain maturity. Upon her arrival, Star is given a family to help guide her, so she moves in with the Diaz family, which includes teenage son Marco. Star takes Marco with her as she battles villains -- both in their high school and throughout the universe -- as she attempts to protect her powerful wand.
