On their day off from Pokémon School, Ash and his Pokémon are left home alone when Professor Kukui is called away. After some mishaps with laundry and cooking, Ash goes shopping and runs into Sophocles at the mall.

After Team Rocket causes a glitch in the security system, Pikachu and Togedemaru get separated from their Trainers—and then the power goes out! Computer whiz Sophocles soon fixes the problem, but by the time he and Ash meet up with their Pokémon, the villains have found them first. Togedemaru and Pikachu team up to defeat Team Rocket, and then Professor Kukui arrives to take the boys out to dinner!
