Meg Gorton finds herself alone and lonely in Florida. Three years earlier, she told her husband, Gary, where he could find her and asked him to take care of Moses, their black Labrador. She'd tried to talk Gary into moving. They both needed a fresh start after a painful loss. Now, Meg has a plan to finally bring Gary to Gulf Breeze. She wants him to bring Moses to Florida so she can see Moses one last time. Although Moses is just a dog, it doesn't take long for him to learn they are going on a road trip to see Meg. He misses her and senses Gary's loneliness. He also knows he's an old dog and that his time is near, but there are still important things only he can do.
