Harley is stuck in the middle, so navigating life as a Diaz requires a little extra ingenuity. When a waterpark installs one of Harley’s inventions, the Diaz family gets to vacation there for free! Then, Harley and Ethan partner up to make a TV commercial for their Dad's store. And on school picture day, in true Diaz fashion, things go awry for Rachel, Georgie and Ethan. No matter what happens, Harley knows that everything will work out, as long as the family sticks together.
