Tormented by desire throughout his adult life, Li Da (played by Swang) longs to become a monk, believing that only by abandoning lust can he find peace. Yet his master, the monk Kongjian (played by Zeng Qiang), insists his worldly attachments remain unresolved and sends him to Leifeng Pagoda for one final trial. Imprisoned within the tower is a mysterious and handsome Black Snake Demon (played by Araw), who sees through Li Da's deepest desires and claims to be their living embodiment. As the two spend day and night together, the primal desires Li Da has suppressed for years begin to unravel. When the trial reaches its end, Li Da must choose between embracing his true self or rejecting all earthly desires. The decision he makes will forever change the course of his life—and set him on the path to becoming the legendary Fahai.
