Xu Zhixia and her four roommates experience a collective rebirth, returning to the snow mountain trip that led to everyone's demise. In their past lives, because Tang Keying insisted on bringing her dog into the tent and slashing it open, all six froze to death. In this life, the five refuse to pay for Tang Keying's self-will again, setting up camp early to save themselves. Facing Tang Keying's threats, rumors, and malicious harm, everyone holds their ground and preserves the evidence. Ultimately, Tang Keying reaps what she sows, suffers severe frostbite, and drops out of school, while the five girls are successfully rescued and reclaim their lives.
