The story follows three discharged special forces soldiers who work as mercenaries in Southeast Asia, survive life-and-death battles, and return home, only to go back to the battlefield for revenge. The main cast should include the three protagonists and the antagonists. Chen Gang, the assault specialist, is fierce and headstrong, making him well suited to drive the action. Li Ming is a sniper, perceptive and devoted to his family; his family tragedy can create an emotional connection with readers. Zhao Feng, the tactical planner, dies early, but his death should leave clues that influence the later plot. As for the antagonists, Chachai serves as the early boss, while Mr. Song is the mastermind behind the scenes. Layered antagonists will heighten the dramatic conflict.
