Lauren wakes at four in the morning in her Los Angeles bungalow, unable to sleep while her husband, Leo, is on a flight. After receiving a text confirming he has landed safely, she reflects on their relationship and the anxiety she experiences whenever he travels—a fear rooted in losing her father in a car accident when she was 15.

While making coffee, she thinks about Leo’s trip: He is interviewing for a director of photography position on a new television series that would require him to work in New York. Lauren is an accountant at a small firm, while Leo is deeply engaged with the creative side of filmmaking.

Leo calls from the airport, and their conversation turns to Lauren’s upcoming fertility clinic appointment. She and Leo have struggled with infertility for years due to her premature ovarian failure, enduring multiple failed procedures. The strain is evident in Leo’s voice; he is exhausted by the process, while Lauren remains determined. The call ends when her father, Dave, arrives at her door before dawn.

Lauren reveals that her father’s death when she was 15 was reversed by her mother, Marcella, using a silver ticket—a magical one-time opportunity to undo a single event.
