In 2003, Fatma Ayar, a teacher at a private high school, assigned her Literature Club students to write letters to themselves as part of PTT's "Letters from the Past" campaign. These letters, intended to be delivered in 2023, were accidentally discovered by Fatma Ayar's daughter, Elif. As these forgotten letters resurface and impact the lives of their original recipients, Elif also faces a truth that will drastically change her own life.
