David, a former US intelligence officer, is determined to live a quiet life in South Korea, but when a name surfaces from an old case, he realizes that the most devastating threat isn't some foreign enemy but someone from within his own bloodline. The show comes up with one of the shocking twists when his estranged daughter reappears in his life, not to mend their relationship but to kill him. This is how David is again forced back into the world of international espionage.
