Jyn ERSO is the daughter of Galen rose, a rebel Scientific engineer, forced by the Empire to build a weapon of mass destruction known as the Black Death.

Together with Captain Cassian Andor and his Imperial droid reprogrammed by the rebels, the girl part was then seeking parent and a door to stop the doomsday plans of the evil Emperor.
