Suppose The Shawshank Redemption is a 1994 American drama film written and directed by Frank Darabont, based on the 1982 Stephen King novella Rita Hayworth and Shawshank Redemption. The film stars Tim Robbins as Andy Dufresne, a banker who is sentenced to life in Shawshank State Penitentiary for the murder of his wife and her lover, despite his claims of innocence. During his time at the prison, he befriends fellow inmate Ellis Redding, played by Morgan Freeman, and becomes involved in a money-laundering scheme orchestrated by the corrupt warden.
Can we infer that "Andy Dufresne was guilty of the murders he was accused of."? Yes, no, or maybe?
