The short starts outside of Tom Cat and Jerry Mouse's house and then cuts to Tom taking a nap but is suddenly awoken by Jerry. To check what the noise is coming from, Tom peeks through Jerry's mouse hole to find Jerry (dressed in a karate gi complete with a Black belt (martial arts)) practicing karate with a punching bag resembling Tom. After Jerry finishes training his spiritual mentor who is a ghost-like figure, appears and asks him if he's ready to take on Tom to which Jerry agrees. After Jerry walks out of his hole he sees Tom at the end of a hallway and becomes afraid of him until Tom starts to mock Jerry and laughs at the thought of Jerry defeating him. Jerry then decides to go and fight Tom to which Tom pulls out a flyswatter and hits Jerry with it multiple times then slingshots him with the flyswatter back to his hole where he runs into one of his walls. Jerry's spiritual mentor appears again and gives Jerry a gong to ring that summons a "Karate Guard" named Momo-sumo (played by Spike and Tyke (characters)) to aid him whenever he needs help.
