In The Sting (1973), Henry Gondorff's elaborate con operation is called the wire.
The wire is a long con designed to make crime boss Doyle Lonnegan believe he can profit from a rigged horse-race betting operation. Gondorff recruits Johnny Hooker and a large group of specialists, each contributing to the false betting office, staged information, or carefully controlled deception.
Paul Newman plays Gondorff, while Robert Redford plays Hooker. The film was directed by George Roy Hill and uses a fictionalized 1930s setting inspired by the confidence games of the period. Its title refers broadly to the con itself, but “the wire” is the specific name given to the operation within the story.
Viewers sometimes answer “the sting” because that is the film's title and a general term for a confidence trick. It is not the operation's specific in-film name. The distinction matters because the question asks for Gondorff's named plan rather than the genre term.
