Milo loves to make his owner Louise happy because she’s his favorite person in the world. While they’re strolling through the park one day, Louise picks a twig up off the ground and says to Milo, “This is Stick”. She throws Stick across the grass and Milo excitedly brings it back to her. Milo doesn’t know why they do this over and over again, but he knows that he can put a smile on her face by running after Stick. So, when Louise throws Stick a little too far, Milo is determined to go the distance too.

Milo starts searching all over the neighborhood for Stick, while Louise simultaneously searches for Milo. Milo sets out on a grand adventure for a little pup, and while his quest takes him all over the globe, he learns that home is where he really wants to be.
