Sara Prescott's eight-year-old son Max wants a dog. But their apartment doesn't allow pets, and the divorced single mom can't afford the certified seizure-alert dog Max needs.

Instead, she and Max volunteer at the Furever Love Animal Shelter. Max forms a special bond with Jett, a big black bully breed and three-time loser who keeps getting dumped.

Animal Trainer Justin Reed comes back home to Magnolia Bay and visits the shelter to find a dog actor for a TV series set in nearby New Orleans. Justin chooses Jett, but the shelter's director rejects his application because Jett needs a finally-forever home, not a job with an end date. The shelter's resident animal communicator proposes a win-win. Justin can use Jett as an animal actor if he also trains Jett as a service dog for Max.

Sara and Justin have no business indulging their mutual attraction. Sara is focused on her son, and Justin will be leaving soon. But Max and Jett have other ideas...
