Checkmate Vol. 4 -

Master artist Park Moon-seob invites Eunsung, a former pupil with whom he had a very public falling out to attend his exhibit. Surprisingly, Eunsung accepts the invitation, but with his newfound ally Soohyun as a plus one. What Eunsung doesn't know is that the gallery centerpiece is another portrait of him, created and exhibited without his permission. This leads to another shouting match between the two artists. And while Soohyun is able to restrain his fellow reporters from publishing photos of the fight, he isn't able to control Moon-seob's mounting anger and jealousy. As insurance, Soohyun tries to win over an older colleague of his to their cause. But against a powerful and sadistic man like Moon-seob, is there really safety in numbers?
