Vivi is an ambitious tech executive who once believed marriage and motherhood had no place in her life. Shu, born into privilege, is a gentle but drifting lawyer who dreams of a slower, unburdened existence. The two first met in a high school band and, years later, reunite, marry, and choose to bring new life into the world. Confined to a delivery room and an extended period of waiting, the couple are forced into difficult honesty. What begins as an intimate ordeal gradually expands into a pressure cooker of family drama, where unspoken expectations and old wounds refuse to stay contained. The arrival of family members and a former lover brings long-suppressed tensions to the surface. Over the course of 36 hours, before the child is born, the marriage is pushed to a breaking point—opening the possibility of change, responsibility, and renewal—at a moment when life and death feel perilously near, and yet nothing is certain.
