When heavy snow seals off the mountain, a pregnant white snake endures a frenzied assault from a flock of eagles without fighting back, all to protect the young inside her. Her scales are torn apart, and her life hangs by a thread. Old Chen, a passerby, sees this and, heedless of danger, swings his rusty woodcutter's knife to desperately drive the eagles away. After narrowly escaping death, the old man shifts from initial fear to awe—he realizes the giant snake would rather die than yield, all to protect her child. This maternal love that crosses species moves the lonely old man, and he lowers his guard and his weapon. In the wind and snow, man and snake forge a silent pact, and the curtain rises on a tale of redemption and repayment.
