 Roger, Anita and their canine clan are packing for the big move to Dalmatian Plantation, a home in the country with plenty of room for the 101 pups and far from the clutches of Cruella DeVil. The feistiest pup, Patch, feels lost in a sea of spots and longs to be a one-of-a-kind wonderdog like his TV hero, Thunderbolt. While watching the Thunderbolt Adventure Hour, Patch hears about a chance to appear on the show while it s filming in London. However, the family move will interfere with Patch s opportunity - until he s accidentally left behind in the commotion. Patch heads for the audition to meet his hero. Meanwhile, Thunderbolt s "trusty" sidekick, Lightning, reveals that the producers of the show want to replace Thunderbolt with a younger dog. In order to save his job, Thunderbolt decides he will go into the real world and perform an act of true heroism to prove himself. A veritable reference book to Thunderbolt s many adventures, Patch provides the perfect guide for the TV star in his attempts at real-life heroics. As for Cruella DeVil - she s back and more obsessed with Dalmatians than ever. At first, she s able to calm her frenzy through an affiliation with a spot-fixated artist.
