Sihyeok Cha, better known in the underworld as the legendary assassin known as the Red Shirt, decides to leave behind a lifetime of bloodshed and violence. Hoping to build a peaceful future with his beloved wife, Miju, and their unborn child, he retires from the world of killers and criminal organizations once and for all.

But the past refuses to let him go.

When tragedy shatters the quiet life he fought so hard to protect, Sihyeok is forced back into the ruthless underworld he thought he had escaped. Old enemies resurface, rival crime syndicates wage war, and the bonds forged through blood prove impossible to sever.

Driven by grief and an unbreakable resolve, Sihyeok must once again become the deadly man the underworld fears, fighting through a brutal conflict where survival demands violence and the battle is only just beginning.
