Hae-woong, an assembly member candidate, is taken out of the running because he became a thorn in the side of a local bigwig, Sun-tae. Hounded by loan sharks, due to defaulting a campaign loan, he decides to get his hands dirty. He steals classified government’s information about an urban development plan and obtains the help of a local gang leader, Pil-do, by promising hefty real estate profit. Now Hae-woong re-enters the race and tries to take revenge on Sun-tae. Unbeknownst to him, his messy journey through politics has only just begun.
Unfortunately the movie The Devil's Deal is not yet available on HBO Max.
