The film focuses on Shangguan Hong, a freshman at Chaozhou University, who joins an all-girl modeling team at school and falls in love with the team's captain Qi Qi at first sight. In order to gain the affection of the goddess, he sacrifices his sexuality to lure his best friend Liu Chuan to join the team, starting an ambiguous love triangle.

The story starts because of one journey. Seven people who have never met before climb aboard the same ride that goes into a seemingly endless tunnel. Despite the countless trials, corpses that mysteriously appear, past acquaintances that returned from the dead and an unseen danger threatening to swallow them whole, it's as if they are trapped in an enclosed space where there is no escape.
