The anime \"Solo Leveling\" immerses us in a world where humanity faces the threat of monsters breaking out of portals in dungeons. The situation is extremely unpredictable, no one knows where and when the next gate will appear. Armies are powerless against these monstrous creatures. The only defense is teams of hunters descending into the dungeons to eliminate the threat. If they succeed, the portal will close, removing the danger. Among the hunters is Sung Jin-Woo, whose task is to fight small monsters. Despite his efforts, he cannot increase his level and earnings. He needs money to treat his mother, who is in a coma. Everything changes when he discovers an unexplored dungeon. After being defeated, he gains a new ability - the ability to teleport to a parallel world where he becomes stronger and faster. His goal is to become a top-class adventurer.
