Britt Reid is the irresponsible and spoiled son of Los Angeles' most prominent and respected newspaper publisher, who lives a life of luxury without purpose or ambition. His life takes a drastic turn when his father, James Reid, dies under mysterious circumstances, leaving Britt his vast media empire. Faced with newfound responsibility, Britt fires the staff of his father's mansion but retains one employee, Kato, who reveals himself to be not just a mere coffee maker but a skilled inventor and martial artist. Inspired by Kato's abilities and seeking a purpose, Britt decides they should become crime-fighters to avenge his father's death and imprint a legacy beyond journalism.

With Kato's technical knowledge, they retrofit a car, the Black Beauty, equipped with advanced weapons, and set out to make a difference. Posing as criminals, they plan to infiltrate the city's underworld to bring down the real threats. As they dive deeper, they become targets of the city's most dangerous crime boss, Benjamin Chudnofsky, who has united all of Los Angeles' gangs under his rule. The two must navigate a world of crime, corruption, and violence while trying to maintain their secret identities and living up to the legacy of Britt's father in their own unconventional way.
