Q:Build a movie plot around this: Why does Jim leave the cabin? So that the FBI will chase him and not Mimi.
A:
A recently widowed single father, Jim Grant (Robert Redford), is a former Weather Underground militant wanted for a 1980 Michigan bank robbery and the murder of the bank's security guard. He has been hiding from the FBI for over thirty years, establishing an identity as a defense attorney near Albany, New York. When Sharon Solarz (Susan Sarandon), another former Weather Underground member, is arrested on October 3, 2011, an ambitious young reporter, Ben Shepard (Shia LaBeouf), smells an opportunity to make a name for himself with a national story.
