It all begins at Mr. Porter’s café where Hailey reports about the pies. Mr Nibbles wants some pies but Mr. Porter reminds them that he puts some food cover. Hailey Dailey then reminds about the Paw Patrol and then heads to go look for them. At the Lookout, Ryder and the pups are blowing bubbles, playing with Chase commented a snowman bubble, Zuma commented on the worm bubble and Skye commented on Rubble’s bubble hat and which they laughed.
Hailey Dailey then revs for the Lookout and Mr. Nibbles turns to the Copycat. Copycat begins to scheme but Mayor Humdinger meet him. Mayor Humdinger has plans to taste some pies but Copycat has an evil plan to get pies for himself. First by molding energy tools and then heated it up and then zooms around The Café, Town Hall and the docks trapping the civilians, including Hailey inside. Mayor Humdinger soon changes to his sidekick attire and then Copycat has the idea. He then takes the mayor up to the top of the Dome by whirlwind and then empowered them with heat and drills the door and he ordered Mayor Humdinger to guard the door as it was the only way in and out. Hailey caught the opportunity to report and as she about to get the camera, she noticed that Mr. Nibbles is gone. She searched for him and then relieved. While the civilians get separated from their friends outside the dome. Mayor Goodway then decided to call the PAW Patrol,
Ryder received the call and then begins to rally the pups and then gives them the orders: Rocky and Rubble to breach the dome. At the dome Mayor Goodway, seemingly panicking urges the citizens to calm down and gave hope. Which the Copycat disagreed and decide to use his super speed to steal the pies for himself, deface the town hall and got a tummy ache.
The trio are at the outside of the dome. Rocky tried to breach it with a hammer only for him to noticed the barrier is stronger like his energy tools, Rubble tried his battering ram but knocked back. Copycat taunted them for a pathetic attempt to break the dome. Ryder then begins to call on Skye to scout above. Mayor Humdinger asked why he got the worst job and falls off the dome and into the bushes. Mayor Goodway sees Skye. But Copycat gone outside the dome and shove Skye out of the air causing Ryder to catch her. Skye deduced that the Copycat made the dome and noticed he got away. Ryder decides to call in additional reinforcements: Chase, Marshall and Zuma.
The pups begins to scout for a way in. Zuma found a way via the water at the pier. Ryder ordered them to charge up. Zuma encased himself and his vehicle in an energy bubble and Marshall tosses him into the sea and managed to get into the dome. The people inside are desperate to seek help while Hailey is disgruntled that she is stuck too. The Copycat appeared before the citizens and demands that he can do whatever he wants without the paw patrol saving them. Zuma reports that he’s inside and then begins to chase the Copycat out of the dome. Chase and Rubble sees the door as the Copycat flees. Chase and Rubble then charged up then uses the wrecking ball and supersonic bark to crack and destroy the dome saving everyone.
Mayor Goodway thanks the Paw patrol while they eat the pies. Ryder then tell her to yelp for help. Mayor Humdinger then arrives and asks if there is pies. But Mr. Porter then replied she give the last batch to Mr. Nibbles and Hailey. Hailey then noticed Mr. Nibbles had a tummy ache and give him a piece of pie. Mayor Humdinger’s smile turned sour as Chickaletta steals the pie slic and pecks on it.
