A new teaching system arrives at the hall and the boys hate it and and try to get rid of it in secret. Bruno's plans never turn out the way they planned so guess who had another plan. The system only holds double digits so once you reach a certain amount something. The boys can't figure it out until later in the movie but Bruno finds out what happens.

Ellie O'Brien (List) is trying to juggle rhythmic gymnastics and troubles with her best friend. Meanwhile, classmate Jack Malloy (Bertrand) is struggling to live up to his brothers' hockey-star legacies and his dad's high expectations and tough-love approach. When a text argument about whose life is easier gets out of hand, Ellie and Jack trigger an explainable real-life swap. As each tries to navigate the other's life, hilarity ensues when Ellie (as Jack) learns about brotherly bonding and hockey lingo, while Jack (as Ellie) has to decipher girl code and experiences a spa day. With a rhythmic gymnastics championship and a spot on the varsity hockey team on the line, they must figure out how to get back in their own bodies before the swap becomes permanent. As they are forced to literally walk in each other's shoes, they gain empathy for one another and learn valuable lessons about their own lives.
