Suppose The Shawshank Redemption is a film adaptation of a Stephen King novella, directed by Frank Darabont and starring Tim Robbins and Morgan Freeman. The movie tells the story of Andy Dufresne, a banker who is wrongly convicted of murder and spends years in Shawshank State Penitentiary, where he forms a friendship with Red, a fellow inmate.
Can we infer that "Andy Dufresne is guilty of the murder he was convicted for."? Yes, no, or maybe?
