Sophia arrives at her best friend Victoria's birthday party expecting champagne and old jokes. Instead, the woman cutting the cake is not Victoria. The smile is wrong, the stories are rehearsed, and every guest plays along. Sophia keeps her own smile fixed and starts asking small questions, watching the imposter's answers slip.
Piece by piece Sophia pulls the thread: a borrowed identity, a forged past, and a circle of people who needed Victoria gone. The closer she gets to the truth, the more the conspiracy turns toward her. To avenge her friend she has to stay inside the lie, smiling at the people who killed her, until the last thread snaps.
