Max, a somewhat rumpled rottweiler working in the K9 NYPD branch (special police forces in the US, consisting of guides and their dogs), unknowingly entwines federal agent Frank Mosley in an operation to catch smugglers of a small panda named Ling-Li. The takeover of the panda is to take place during the famous Las Vegas party, where the annual dog show takes place. A prestigious competition gathers the rich, and the dog finalist is worth millions of dollars.

Frank, to participate in the event, so get the opportunity to penetrate into the environment, must stand for the competition. Naturally, with a dog. For Max, a police dog, it's quite a challenge. It does not help the fact that Max thinks Frank is a loser. He knows that both of them do not fit into the glamorous world of glamor.
