Kate, an overprotective single mother and overworked veterinarian, already has her hands full running an animal shelter and sheltering her fragile, ailing son Jasper from life. And then an extraordinary dog, Whistler, appears. Scarred, badly mistreated, and preternaturally wise, Whistler forms an immediate bond with Jasper - the two seem to communicate without words. But that's only the beginning, because Whistler has a mission and a message: to make Jasper, and Kate, find the most in every moment, to fully embrace what lies before them - no matter how heartbreaking.
