A salaryman gets kidnapped and discovers he's more alive bleeding through a firefight in the South China Sea than he ever was in a conference room. Revy doesn't recruit him because he's valuable, she recruits him because watching him break his own rules is the most interesting thing that's happened to her in years. The show spends no energy on whether any of this matters in the larger sense, it only cares that the bullets are real and the people pulling triggers have reasons that make sense to them alone.

Rokuro Okajima is a salaryman worn down by the mundane: drinking with clients, abusive superiors, the slow suffocation of routine. A simple delivery job to Southeast Asia promises nothing but more of the same until pirates intercept his vessel and take him captive. Rebranded as "Rock" by his captors, he ends up at the mercy of a crew of mercenaries sent after the disc he was carrying. Revy, the crew's brash gunslinger, holds him hostage in the belief that he could fetch a ransom. The disc hides a secret Rock knows nothing about, and it throws captive and captors alike into chaos. When his own company refuses to pay and leaves him for dead, Rock surprises everyone by joining the crew that kidnapped him. Now living in Roanapur, a city overrun by crime and corruption, he must let go of his past, clash with Revy, and make hard choices under pressure without losing his humanity. The show mixes gritty action with thriller tension and drama as an ordinary office worker is pulled into a criminal underworld.
