When Mister Mack gets arrested for supposedly robbing the bank, it is up to Rover the dog and the Mack children to rescue him and find their Guinness-record-breaking mother who is running around the world.

A talking dog, the Mack children, and the small elf-like Gigglers themselves must try to stop the prank that the Gigglers have mistakenly set in motion to punish Mr. Mack for being mean to his children.

Siobhán and her father continue to feel sad in the years following the death of Siobhán's mother, until Siobhán follows the advice of a mysterious woman.
