Eight-year-old Lily accidentally ends up on a high-speed conveyor belt while trying to retrieve her doll. Engineer Jack hears her cries for help, but his boss, Ethan—obsessed solely with fulfilling orders—prevents him from shutting down the machinery. A web of lies, old footage, and tampered surveillance footage repeatedly thwarts rescue efforts. It is only after Jack risks his life to save the girl that Ethan realizes the child he had repeatedly consigned to death is, in fact, his own daughter.
