Black Knight

Actor Kim Woo Bin made a comeback to the entertainment scene with his drama "Black Knight," after taking a break for health reasons. Based on Lee Yun Kyun's webtoon of the same name, "Black Knight" is an action-packed survival story set in a future world where people need oxygen tanks and masks from the government to survive.

Kim Woo Bin plays Agent 5-8, a top-performing government agent. His job is to hand out oxygen tanks and masks to South Koreans who survived after a meteor turned their country into a desert. But he's more than just an agent; he's also a secret hero.

Agent 5-8 and a few others secretly help people who aren't as fortunate as the "chosen ones" who have easy access to oxygen. They distribute medical aid and food. However, the government, which wants to get rid of the less lucky citizens, finds out about their actions. This leads Agent 5-8 and his group to start fighting against the government.
