Architecture student Lin Jue receives a mysterious “Lucky Egg” and is pulled into a supernatural survival game known as the Devil’s Hunting Ground. Medical student Song Hanzhang saves him during the first ordeal, and the two form an alliance built on complementary strengths and uneasy trust. Each new trial pits players against strange creatures, desperate competitors, and rules they barely understand while Lin Jue tries to learn who designed the game and why they were chosen for it.
