Based on the novel "The Hundred and One Dalmatians" by Dodie Smith. Songwriter Roger Radcliffe lives in a bachelor flat in London, England along with his dalmatian Pongo. Bored with bachelor life, Pongo decides to find a wife for Roger and a mate for himself. While watching various female dog-human pairs out the window, he spots the perfect couple, a woman named Anita and her female dalmatian, Perdita. He quickly gets Roger out of the house and drags him through the park to arrange a meeting. Pongo accidentally causes both Roger and Anita to fall into a pond, but it works out well as the couple falls in love. Both couples marry. Later, Perdita gives birth to 15 puppies. One almost dies, but Roger is able to revive it by rubbing it in a towel (because of which, they would name it, "Lucky"). That same night, they are visited by Cruella De Vil, a wealthy and materialistic former schoolmate of Anita's. She offers to buy the entire litter for a large sum, but Roger says they are not for sale. Weeks later, she hires Jasper and Horace Badun to steal them. When Scotland Yard is unable to determine the thieves or find the puppies, Pongo and Perdita use the "Twilight Bark", normally a canine gossip line, to ask for help from the other dogs in London. Several other dogs from around the countryside come to help free the dogs, who Cruella wants to make into dog-skinned fur coats, and they become friends with 84 more puppies, and it's up Roger and Anita to decide whether or not to keep all 101 dalmatians.
This is a TV spot, which unfortunately cuts off at the end, for a 70s rerelease of the movie.
