Realizing she’s nearing the end of her life, 14-year-old Abby the Whippet and her human, Mark, embark on an epic cross-country road trip. From captaining a yacht to riding It’s a Small World, making friends with a dolphin and a deer, even peeing on the world’s tallest trees, Abby does it all! By the way, whose list is this anyway… Abby’s or Mark’s? Does it really matter? As the journey unfolds, we realize that all they really want is quality time together. And incredibly, the Universe intervenes; Abby starts aging in reverse, and their three-week bucket list trip morphs into the three-year journey of their lives!
