It's time for the annual witches' field day! Magical families travel from all over for some friendly competition. Mateo is excited since it will be his first time participating in the events. Nina is excited too--and determined to beat her long-standing rival Becca, a witch who doesn't always play fair. As the tournament gets underway, Nina and Mateo will have to learn to work together and bring out each other's strengths if they want to have a chance at winning.
