Rubble is with Mayor Goodway and her uncle, Otis Goodway, who's a little hard of hearing, as he attempts to search for gold in the creek. None of them notice Mayor Humdinger watching from behind a tree after hearing the word "gold" from Uncle Otis. However, Otis's equipment is all worn out and rusted through, leaving him unable to do any prospecting. Luckily, his niece knows just who to call for help and contacts Ryder.
At the Lookout, the pups are playing tug-of-war when they realize that the other end of the toy was caught on the branch of a small tree. Ryder soon gets the call from Mayor Goodway asking for help and summons the pups. In the rush, Marshall gets a bird's nest on his head as the bird falls asleep. Marshall tries not wake it up, but trips over a stuffed toy as he enters the elevator. As a result, the bird wakes up and flies off, but soon returns to retrieve its nest from Marshall's head. Afterwards, the pups head topside to get their orders from Ryder.
Ryder needs Chase to provide security for the claim, and Rocky to convert his truck's forklift to a gold-panning machine to help out. With that, the team deploys to meet up with Mayor Goodway, and Mayor Humdinger has to hide to avoid being spotted as the team arrive at the claim. With new equipment for Uncle Otis, the team start their search for gold. Soon enough, just as Chickaletta is about to eat what she believes to be corn, Otis catches the shiny rock and reveals it to be a gold nugget. As the team find more, Humdinger and Cat Chase, watching from the tree, decide to steal the Goodways' gold for themselves, and Humdinger summons the Kitten Catastrophe Crew. However, he ends up falling out of the tree and is discovered by Ryder. Luckily, he concocts the ruse that he wants to help, and Ryder buys it.
During the search, once the pile is large enough, Humdinger uses a rock candy ring as a diversion, saying it's a diamond, allowing the Catastrophe Crew to load all the gold into a trailer attached to their carrier and allow them to escape, so by the time Otis discovers they've been tricked, Humdinger is already making his getaway.
Ryder, Rubble, Chase, and Rocky give pursuit, following him all the way back to their hideout in Foggy Bottom. Thankfully, in their haste to get into their hideout, Humdinger and the kittens then bring the gold inside. By the time the PAW Patrol got to his hideout, it is too late to stop him. Mayor Humdinger had already melted all the gold down into a statue of himself.
Back in Adventure Bay, Mayor Goodway was upset to not be able to make the new statue of Chickaletta that would of been made from all the gold. Otis then tugs at his suspenders, causing them to come loose and leave his pants around his ankles, much to everyone's embarrassment.
