The Last Kiss plot recap, spoiler-light
High school student Laurel Hansen anticipates a romantic fairy tale on Valentine's Day, but her life turns upside down when a bridge collapse leaves multiple students and supervisors struggling for survival. After kissing her crush Leo, Laurel is struck by a terrifying vision revealing that he is doomed to die in a bizarre murder spree targeting her inner circle. A year later, Laurel deals with lingering trauma, estrangement from her former best friend Poppy, and distressing premonitions of her mother Diane perishing in a house fire.
When Laurel begins dating classmate Evan, a subsequent kiss triggers a terrifying new vision showing Evan and another student being fatally stabbed. Dismissed by Principal Randy Yang and warned by Diane about a potential return to the Brookside mental hospital, Laurel resolves to uncover the killer before the premonitions become reality. She reconciles with Poppy and attempts to eliminate suspects, all while navigating mounting tension, broken relationships, and suspicious deaths surrounding the survivors of the original bridge disaster. Additionally, Laurel investigates the local conservatory where Pauline was found hanged, further deepening the mystery of who might be hunting the bridge survivors and leading her to suspect Leo's brother Noah before uncovering the startling truth behind the entire sequence of tragic events.
