Butterbean is in a funk. After watching a documentary of famous dogs in history, she wants to be a real dog. Real dogs have jobs. Real dogs are heroes. But Butterbean? Butterbean is nothing but a house pet. Never mind that she and her friends have been super spies, ghost hunters, and part of an International Crime Syndicate. There's nothing to spy on and no more ghosts to hunt.

A chance to be a real dog comes when Butterbean rescues a puppy cornered by the nefarious Animal Control Man. But she may have gotten more than she bargained for when that one puppy turns out to be part of a whole pack. Now it's up to Butterbean and the gang to find these puppies new homes before their owner, Mrs. Food, finds out that they've been hiding their new furry friends in the apartment!
