About this drama
Three years ago, Jack Carter and Ryan Cole went undercover in the Golden Triangle to take down a ruthless crime network. But a traitor exposed them, and Ryan was killed. Now Jack is back with one mission: destroy the five crime syndicates that took his brother from him and hunt down the mole who betrayed them. As enemies close in, Jack protects Ryan's family, pays his mother's medical bills, and unleashes a brutal reckoning no one will survive.
