Brief description
Saw Gerrera shows Jyn Erso a message he had received of Galen Erso, her father. He tells her about a weapon he created for the Empire and how to destroy it. Although he is working for the Empire it's against his will and he only did this to protect her when she was a child. But now he is trying to redeem himself by giving the rebels instructions on how to destroy this weapon (The Death Star).
