Cormac, a golden retriever who has always been afraid of thunderstorms and lightning flashes, runs away one stormy night while his master is away. So begins a strange adventure that lands Cormac in the back of a red pickup truck driven by a mysterious woman, takes him to a series of dog pounds and rescue shelters, and ultimately brings him to the suburbs of Connecticut. His owner, meanwhile, devastated by Cormac’s disappearance and trying to juggle a family, a book tour, and writing his new novel, becomes determined to solve the “dog-napping” case. With the help of the local veterinarian, bookstore colleagues, animal rescue employees, and old friends, he picks up on Cormac’s trail and watches his small-town community come together in search of his lost companion.
