As a nasty thunderstorm is moving in on Adventure Bay, Farmer Al soon takes notice and ushers his cows and Corny to the barn to hunker down and take shelter, but a thunderclap spooks Corny and causes him to run off. Unable to pursue him on his own, Farmer Al calls the PAW Patrol.
At the Lookout, the pups are packing up their toys and putting them in their pup houses to keep safe from the storm when Ryder gets Farmer Al's call for help finding Corny. Ryder summons the pups to the Lookout, and Marshall crashes into the elevator due to being blinded by a small bunch of leaves blown in his face by the storm winds. Once topside, Ryder assigns Chase in his spy gear and Skye to help him find Corny. The team deploys and sets off to find Corny.
After getting directions on where Corny went from Farmer Al, Ryder and Chase reach a cliff where Skye spots Corny on a ledge just underneath, trapped and unable to escape. When they can't convince Corny to come with them, they have Skye airlift Corny to take back to Farmer Al's. However, with the storm closing in, and the lightning dangerously too close for comfort, Ryder has Skye take the long way around the storm to get back to Farmer Al's, using the lights of Adventure Bay to guide her.
However, the storm manages to cause a blackout in the city, leaving Skye basically flying blind with no way to find her way back to Farmer Al's. Knowing she needs help, Ryder summons everyone he can contact for assistance, including Jake and Everest, Mayor Goodway and the Porters, Cap'n Turbot, and the rest of the pups. With their help in providing illumination to help point the way back to Farmer Al's, Skye and Corny make it back safely, and the power is soon restored shortly thereafter.
Corny hops up on some hay bales to oink his excitement from flying with Skye, and Ryder makes a joke about how when pigs do fly, Corny would be the first one, much to everyone's amusement.
