"Cobra Kai" follows the lives of Daniel LaRusso and Johnny Lawrence, two characters from the original "Karate Kid" film series, as they reopen the Cobra Kai karate dojo. The series explores their perspectives and the impact of their rivalry on a new generation of high school students, including Johnny's student Miguel and Daniel's daughter Samantha.

Themes of redemption, mentorship, and the consequences of one's actions are central to the plot. The show also delves into the gray areas of character morality, challenging the notions of hero and villain. The rivalry between Daniel and Johnny is rekindled, and the series skillfully blends nostalgia with contemporary storytelling, addressing the complexities of life and karate in the present day.
