After refusing to perform unnecessary high-priced surgeries, independent veterinarian Claire Morgan breaks ties with Victor Crane, the owner of a chain pet emergency center, and opens "Second Chance Vet" across the street. With her ability to hear animals' inner voices, she teams up with Duke, a tabby cat who appointed himself clinic manager, and a group of stray animals to treat pets that Victor has misdiagnosed and overcharged. As her investigation deepens, she discovers that Victor not only sells unregistered veterinary drugs but also uses animals as product test subjects. With the help of pet livestreamer Maya, retired K9 handler Ryan, and a black cat named Shadow, Claire gathers evidence, fights back against public smear campaigns, and ultimately exposes Victor's illegal network, establishing a community animal rehabilitation center.
