Star Butterfly is a magical princess from the dimension of Mewni and the heiress to the royal throne of the Butterfly Kingdom. As per tradition, she is given the family heirloom wand on her 14th birthday. After she accidentally sets fire to the family castle, her parents King River and Queen Moon Butterfly decide that a safer option is to send her to Earth as a foreign exchange student, so she can continue her magic training there. She befriends Marco Diaz and lives with his family in suburban Los Angeles while attending Echo Creek Academy. Going in a series of misadventures using "dimensional scissors" that can open portals, Star and Marco must deal with everyday school life while protecting Star's wand from falling into the hands of Ludo, a half-bird half-man creature from Mewni who commands a group of monsters.
