Madison knows her fourteen-year-old daughter Abbie is struggling. She wishes she could give Abbie stability, the promise of a forever home in Millbury, but she is scared to stay in one town for too long, and every day Abbie seems more anxious. Until a chance encounter with a beautiful, boisterous golden retriever puppy called Duke changes everything... Duke bounces into the community centre where Madison is working and when Abbie meets him she stops pacing the room. Duke is tugging his owner, seventy-five-year-old Arthur, along for the ride, and instantly Madison sees a way she and Arthur can help each other. She offers to train Duke so that Abbie gets to see him, and from that moment the four of them become a family. Madison finally feels like she has a second chance at life and a reason to stay in town, but when her past catches up with her they are all at risk. Duke may have united this family, but will he be able to keep them together?
