We return to the beautiful Yorkshire village of Holmfirth where our famous trio of troublemakers has officially become a quartet. Spreading their usual chaos and mayhem wherever they go, Clegg, Truly, Alvin, and Billy are back for more mischief. Follow the boys as they meet a stranger planning to float to Ilkley on an inflatable swan, encounter a womanising flower arranger, and come up with a devilish plan to get rid of Clegg’s unwelcome cousin, Aubrey. Clegg gets stuck in a tree while trying to prove a point, and Alvin trains to become an astronaut. All this and Nora Batty goes blonde.
