White Snake (BAI Suzhen), who has practised supernatural power in Mount Emei for a thousand year, admires human warmth as Green Snake does. Incarnated into humans, they come to the West Lake, where BAI Suzhen comes across her benefactor XU Xian. Falling in love with each other, they get married and open a clinic, Baohetang, to treat sick people. Monk Fahai from the Jinshan Temple, devoted to keeping peace in the world, does not tolerate human-fairy marriage, so he advises XU Xian to test BAI Suzhen with realgar wine at the Dragon Boat Festival. That very day, the people propose a toast to XU Xian and BAI Suzhen to thank them. Finding it difficult to refuse such kindness, BAI Suzhen cannot but drink the realgar wine, with her true feathers revealed, scaring XU Xian to death. Waking up, BAI Suzhen feels extremely grieved, and thus risks her life to go to the Mountain of Immortals to seek glossy ganoderma, a magic herb. XU Xian is thus brought back to life.
Recovering from his illness, XU Xian is full of misgivings and steals away to the Jinshan Temple in order that Fahai should point out the right way to him. However, he gets detained in the meditation abode by Fahai, not to return days later. BAI Suzhen goes to the Jinshan Temple with Green Snake and pleads with Fahai to release XU Xian, only to be turned down. Having reached the end of her forbearance, BAI Suzhen gathers water to flood the Jinshan Temple. Fahai invites a general with magical power to assist in fighting, whereas BAI Suzhen, who will soon be giving birth to a child, begins to flag, retreating one step after another. Luckily, the water demons escort her through the tight encirclement.
BAI Suzhen passes by the Broken Bridge over the West Lake, where she remembers the past, overwhelmed by grief. Touched by the true love between BAI Suzhen and XU Xian, Fahai lets XU Xian go for reunion. Indignant at what he has done, Green Snake raises her sword to kill XU Xian. BAI Suzhen tries her best to dissuade Green Snake from doing this and tells the whole story to XU Xian. Moved by BAI Suzhen’s true love for him, XU Xian makes peace with her. The couple returns home then.
