Lee Na-yeon, a Hyosan High School student once consumed by selfishness, caused the death of her classmate Han Gyeong-su in a past life. She awakens to a mysterious second chance, thrust back to the final moments before a zombie outbreak ravages her school. Burdened by guilt and fueled by a fierce resolve to atone, Na-yeon carries the dark memories of her previous life-blood, screams, and betrayal-as she strives to alter the fates of her friends: Cheong-san, Gyeong-su, On-jo, Nam-ra, and others, including those she once dismissed like Min Eun-ji and the virus's first victim, Kim Hyeon-ju.
Caught between remorse and determination, Na-yeon slowly proves her transformation to those around her. Yet, their trust remains fragile, and every step toward redemption is tested by shadows of her past and the relentless threats lurking nearby. Redemption is a tale of a girl's struggle to right her wrongs, confront monsters within and without, and discover the true meaning of love and sacrifice amid the chaos of a zombie apocalypse.
