Fifties Professionals

Three seemingly ordinary but secretly dangerous middle-aged men whose destinies bring them back into action. It’s a reality-based action comedy about professionals in their fifties who have lived half their lives, depicting the bittersweet everyday lives of three middle-aged men you might find anywhere and the even sadder reality of men who were once at the top of their game.
Jung Ho Myeong, a professional National Intelligence Service agent who blends into even the most dangerous situations like air. Once South Korea’s top black ops agent, he now finds himself at a crossroads, physically and emotionally past his prime.
Bong Je Sun, a former elite operative from North Korea’s Ministry of People’s Armed Forces. Once the most fearsome human weapon the North had ever produced, he now suffers from recurring nightmares where he dresses up as a woman and experiences growing depression about his current life, unsure if he can ever return to who he once was.
And the former second-in-command of the most feared gang in South Korea, capable of making people tremble with a single word. Now, however, he is simply a convenience store owner, consumed by worries about his future.
