In a city filled with crime and corruption, a young and carefree playboy named Britt Reid inherits his late father's media empire. Although he initially doesn’t know what to do with the inheritance, his life takes an unexpected turn when he becomes an undercover vigilante. Alongside his skilled mechanic and martial arts expert, Kato, Britt decides to take control of his destiny and fight against the evil plaguing the city, even though his initial approach is more fun than heroic.
With a flashy disguise and a couple of impressive gadgets designed by Kato, Britt transforms into "The Green Hornet," ready to confront the powerful mafia led by the feared Chudnovsky. However, the relationship between Britt and Kato is anything but conventional; while Britt tries to position himself as the "hero," Kato is the true mastermind behind the operation, making it clear on more than one occasion that he is the one in control of the situation.
With the help of their clever gadgets, a good dose of humor, and some electrifying action scenes, the unconventional duo plunges into a whirlwind of adventures. But as they fight to make a name for themselves, they will also have to confront their differences and learn to trust each other to dismantle a vast criminal empire that threatens to ruin everything in its path.
