Quiet, book-loving Chloe heads to summer camp with a crush on star swimmer Jason, but her hopes are crushed when he shares her secret journal with everyone. She decides she is done with him, and Jason jokes that he would rather become a dog than care about Chloe. After a strange storm, he wakes up in the body of Chloe's golden retriever, Max. Chloe alone can understand his barking, and a magical moment can temporarily return him to himself. As they are forced to work together, Jason begins to see Chloe's bravery, warmth, and true worth.
