[1][2] The finale of the film was re-shot after the distribution company requested a change to the original bleak ending.
[2] While fishing and listening to a football game, rail worker Fabio Santamaria hears a woman screaming.
Initially Fabio, still too afraid to go to the police, attempts to cover up his involvement: he buys new sunglasses to replace the pair he lost, he throws away his flannel shirt and boots, shaves off his mustache, and repaints his car.
In the original ending a reporter investigating the story, Don Peppino, confronts the Professor, who drives away.
In the reshot theatrical release, Don Peppino's confrontation of Professor Ranieri prompts him to kill himself, and a final scene relates that the professor has cleared Fabio of the crime in his suicide note, and so Fabio, cheerful in prison, is expecting release.
