When the Bagthorpes are robbed, Grandma decides they must have a family reunion, so the Dogcollar Brigade come to stay. The DB consists of meek Uncle Claude, a reverend, his wife Penelope, who is obsessed with cleanliness and godliness (in that order), and their two revoltingly clever children, Esther and Luke. Their cousins' accomplishments throw the younger Bagthorpes headlong into a search for their own immortality via the Guiness Book of World Records. To get on with their work, though, they must get the DB out of the house.

The Bagthorpes are robbed, and Grandma decides they must have a family reunion, so she invites the Dogcollar Brigade - Uncle Claude, his dreaded wife Penelope, and their two excessively clever and bratty children - to stay. When it emerges that Cousin Luke is working to be the Young Brain of Brittain, all the Bagthorpes develop an obsession with immortality and the pursuit of a Guiness World Record. Meanwhile, the younger Bagthorpes have to come up with a way to get Aunt Penelope and her awful menage out of the house - so it's war once again in the Bagthorpe household.
