In 1911, just two days before the Fourth of July, Lady and Tramp have three well-mannered daughters, Annette, Danielle, and Collette, and a rambunctious son named Scamp. After Scamp makes a mess in the house, Jim Dear chains Scamp to the doghouse outside as punishment. His parents, Tramp and Lady, are distraught that their son cannot settle down and follow house rules. Tramp tries to reason with Scamp, but loses his temper at his son's insistent desire to be a wild dog. Later, Scamp sees a pack of stray dogs, named the Junkyard Dogs, harassing the dogcatcher outside the yard and becomes intrigued. Scamp breaks free from his chain and runs off to find the pack. He finds a young member of the pack, Angel, and she takes him to the rest of the Junkyard Dogs. Meanwhile, Lady walks out to reconcile with her son but is horrified to see that he has disappeared. Panicking, she rushes back in and alerts Tramp and the Darlings start a search party.
