Jyn Erso (Felicity Jones) has never been one to follow rules. Separated from her parents at an early age, she was taken in by Saw Gerrera (Forest Whitaker). He left her on her own at age 16 and she's had to survive in the galactic underworld by cultivating skills in both fighting and cunning.
When Jyn is arrested by the Rebel Alliance, she is asked by Mon Mothma (Genevieve O'Reilly) to join a team in order to retrieve information about the Death Star — a nearly constructed weapon with the power to destroy an entire planet. If the Death Star's construction is completed, the Empire will become unstoppable.
