Andy Carpenter has spent the three years since graduating law school working as a prosecutor in Paterson. But having seen how the system never looks out for the little guy, he leaves to start his own practice as a defense attorney. His office might be a little bit of a dump, but he's excited to make a change. Andy goes to the shelter to adopt a dog, where he meets his beloved golden retriever, Tara, for the first time and feels an immediate connection. The shelter is crowded and Tara's been sharing space with a dog named Sunny. Andy hates to break them up and so asks to take Sunny, too, but since there's a pending criminal case involving the owner, he'll need to get written permission for temporary possession. Andy discovers that Sunny's owner, Frank Tierney, has been arrested for the murder of his ex-boss. But he takes an immediate liking to Frank and his clear dedication to his dog and ends up with his first case along with the two dogs.
