On the Day of Judgment, monsters from other dimensions invaded earth. Thirty-two years later, humans with special abilities called hunters fight the monsters to keep humanity safe. They train in an online game called "Lost City"—but the best player, Jinsoo Kwon a.k.a. "Unknown," is no hunter. He only plays the game to earn money for his sister's medical bills. But when a guild recruits Jinsoo to be a hunter in return for medicine, it's an offer he can't refuse. It's time for this fighting legend to protect his home and his family! (Source: Tapas Media)
