After a solar flare erases all human memory, Thalía wakes up with no sense of who she is and only one physical clue from her past: a C-section scar. In a world where no one remembers their former lives, she begins a search for her missing daughter, guided by fragments, instincts, and a man who claims to remember everything. As new forms of authority emerge from the collapse, Thalía is forced to confront a central question: whether truth comes from memory—or from the choices we make when the past is gone.
