What Leads Up to the Ending
Carolyn, an ambitious prosecutor, is found raped and murdered. Rusty, her ex-lover, investigates and then is charged. His lawyer, Sandy Stern, defends him.
What Happens at the End of Presumed Innocent
At trial, Stern shows that the prosecution's case is full of holes: a glass with Rusty's fingerprints has gone missing from the evidence room, and the forensic evidence that the killing was a sexual assault starts to look strange. Stern also hints that Judge Larren Lyttle, who once took bribes in a case linked to Carolyn, has reasons to want the case gone. The judge dismisses the charges. Later, Rusty finds a hatchet with blood and hair in his basement and realizes Barbara, furious about his affair, killed Carolyn and staged the scene to look like a sexual assault using his semen from their marriage bed. Barbara confesses, saying she meant him to know. Rusty decides to stay silent so their son does not lose his mother.
