The movie begins with an electric scooter chase between Harry and his nan because she didn’t know it was him. Afterwards, Harry is sent to get a chicken for lunch, but they fire a machine gun at him and throw a grenade, which Harry throws into the chicken shed, blowing them up. They then discover that their beloved pet hamster Abu is ill so they take him to the vet. He is almost put down until Harry takes him back home. Ed the vet and his assistant, Kisko, are working for Harry’s neo-Nazi twin brother Otto who was abandoned by his nan in the 1970s, claiming it was because she couldn’t look after them both, and raised by dogs.
After another failed attempt to capture Abu (by disguising as a priest and a nun), Harry and his nan decide to take him on a trip in their Rover P6 to Blackpool for a week before he dies. Ed and his assistant pursue them on the road, until they arrive in “Blackpole” by mistake. The next day, Harry and his nan take Abu on a personal guided tour around the nuclear power plant by the cleaner. Ed and Kisko attempt to capture him again only for him to end up turned into a destructive giant caused by radiation which wears off shortly. While walking on the beach they encounter Barney Cull, a member of the Shell People.
He asks Harry and the others to save his people’s children from a gift shop. They succeed and they are invited back to the Shell People’s cave where Harry falls for the Shell King’s daughter, Michelle. He leaves after being unable to cope living under water. They continue their road trip only to end up in a boxing match where Harry has to fight Kisko to keep Abu. He successfully wins with a free stick of rock. Later on, the car runs out of petrol in the middle of the woods and Harry and his nan leave Abu behind while they search for a petrol station. He’s almost kidnapped again by Ed and Kisko only to leave the car in pieces.
Meanwhile, Otto teams them up with a master of disguise fox. Harry, his Nan and Abu hitch a ride with Justin Bieber and Selena Gomez (actually Ed and Kisko in disguise) and they arrive in Blackpool to see a show. After they finally arrive there, Harry is reunited with Michelle (much to his Nan’s dismay) and Abu is finally kidnapped and replaced with the fox. Harry later finds out and they go looking for Abu. They follow a trail of steak barbecue hulahoops (which is what Otto was left with to eat when he was abandoned) to his hideout where he reveals his plan to turn Abu into a model figurine for his collection as an act of revenge for being deserted. During a fight between the two, Harry’s nan reveals that she got rid of Otto because she kept getting him and Harry mixed up. After being chased away by killer brains, Harry and his nan are saved by the Shell People, to which his Nan accepts his and Michelle’s love. Harry pursues his brother to the top of the Blackpool tower.
His Nan rescues him and Abu in a helicopter when Otto falls to the ground after taking a punch from Kisko after he and Ed thought they were working for the wrong brother. After defeating Otto, Abu coughs up a green felt tip pen which turned out to be the cause of his illness. Ed explains that hamsters like sucking on pens and he gave it to Abu so he would be sick and start this whole plan, even though he could’ve kidnapped Abu at the time. Abu lives and the movie ends with a big end song with everyone in the film. Just before the final credits, a hamster appears on screen, riding on a model train. He gets off at the model station when the train stops. The hamster can only be thought to belong to Harry Hill, but there is no evidence for this.Its a madcap, surreal, silly mayhem. The film rather lulls in the middle when you feel its run out of steam and laughs. The humor is a bit hit and miss, however switch your brain off, and it is mildly entertaining and amusing.
