The film tells the thrilling story of NYPD dog Max (voiced by Ludakis Ludacris) and his human partner FBI Agent Frank (will Arnett Will Arnett) working together to solve the case. A man and a dog, who do not know each other and have very different personalities, were forcibly formed as a result of a rare animal theft. He was then dispatched to Las Vegas to participate in a world-renowned dog show to track down the culprit through undercover operations. And this operation is far more difficult than expected for the "dog-hating" agent Frank and the untidy Max.
