In the early 1940s, a shy and introverted boy named Willie Morris lives in the small town of Yazoo, Mississippi. Willie struggles to make friends and is bullied by his peers. His only companion is his neighbor and father figure, Dink Jenkins, who is later drafted to serve in World War II. Feeling increasingly lonely, Willie's mother persuades his strict father to let him have a dog. On his ninth birthday, Willie receives a Jack Russell Terrier puppy named Skip. Skip becomes more than just a pet; he is a friend who brings joy, confidence, and a sense of adventure back into Willie's life. With Skip by his side, Willie starts to break out of his shell, making new friends and even impressing his crush, Rivers Applewhite.

Skip’s playful antics and unwavering loyalty help Willie navigate the challenges of growing up. Through their shared experiences, Willie learns valuable life lessons about love, responsibility, and the meaning of friendship. Skip’s influence extends beyond his relationship with Willie, as he becomes a beloved figure in the community, bringing people together and teaching them about compassion. However, as time progresses, both Willie and Skip face trials that test their bond and reveal the complexities of life.
