34 years after losing the All Valley Karate Championship, Johnny Lawrence decides to reopen the Cobra Kai Dojo while his school adversary, Daniel LaRusso, runs a successful auto business.
Daniel LaRusso discovers Johnny is reopening the Cobra Kai dojo and is determined to stop it from happening.
Johnny tries to recruit more students; Daniel chaperones Samantha's high school dance; Miguel takes things too far with his bullies.
Daniel's defaced billboard causes tension with Johnny; Johnny's son Robby is embarrassed by his father and his new dojo; the bullying against Miguel escalates and Johnny finds himself motivated in a surprising way.
Daniel uses underhanded tactics to try to drive Johnny out of business; when Miguel defends Samantha's honor at school with his new karate skills, the resulting viral video drives a new wave of enrollment at the Cobra Kai dojo.
Johnny is less than pleased with his new batch of students; Robby takes a job with Daniel with the ultimate goal of angering his father; Daniel inspires interest in karate from an unlikely source.
