Cat and her brother Chicken have always had a very special bond. When Chicken has a ''meltdown,'' Cat’s the one who scratches his back and reads his favorite story. She always knows what he needs. Since their mom has had to work double-hard to keep their family afloat after their father passed away, Cat is the glue holding her family together.

When a summer trip doesn’t go as planned, Cat and Chicken end up spending three weeks with grandparents they’ve never met. With their help, Cat can be a kid again for the first time in years, and the journey she takes shows that even the most broken relationships can be healed if people take the time to walk in one another’s shoes.
