Marcus Blades is a mercenary for hire. His mission is to kidnap a rising R&B singer, but is targeted for death instead. Marcus seeks revenge against those who plot his demise and he wants payment for the job he's done.

Daniel moves to Los Angeles with his mother, Lucille, and soon strikes up a relationship with Ali. He quickly finds himself the target of bullying by a group of high school students, led by Ali's ex-boyfriend Johnny, who study karate at the Cobra Kai dojo under ruthless sensei, John Kreese. Fortunately, Daniel befriends Mr. Miyagi, an unassuming repairman who just happens to be a martial arts master himself. Miyagi takes Daniel under his wing, training him in a more compassionate form of karate for self-defense and later, preparing him to compete against the brutal Cobra Kai.
