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.

Armed with nothing more than twigs, their imaginations and a simple set of rules, a group of 12-year-olds engaged in a lively game of Capture the Flag in the neighborhood woods start dangerously blurring the lines between make-believe and reality. Paint-filled balloons = Grenades. Trees = Control towers. Sticks = Sub-machine guns. The youthful innocence of the game gradually takes on a different tone as the quest for victory pushes the boundaries of friendship. The would-be warriors get a searing glimpse of humanity's dark side as their combat scenario takes them beyond the rules of the game and into an adventure where fantasy combat clashes with the real world.
