According to the official logline, the series will be “centered on David Jung (Kim), an enigmatic, highly unpredictable former US intelligence operative living in South Korea, whose life is blown to pieces when the consequences of an impossible decision from his past come back to haunt him, and he finds himself pursued by Rebecca (Hardesty), a deadly, sociopathic young agent assigned to kill him.”

However, the release date of the series has not yet been revealed.
