When the adventures and antics of Star Butterfly and her boyfriend Marco Diaz get out of hand, it catches the attention of a new evil teenage girl who, with the help of her trusty brother and partner-in-crime, threatens to separate Star from her friends and family forever. Chased from her home in Mewni Creek, Star decides that there's only one thing they can do to get away from her - move to a new place to live! So, Star and Marco, accompanied by their friends - Tom Lucitor, Janna Ordonia, Pony Head, Kelly, and Tad - embark on an epic road trip filled with new friends, dangerous obstacles, and massive parties, even when they crash their van into the sea. This risky journey also forces Star to face how she began fighting monsters, in order to keep her bond with her friends from being torn apart.
