The short version

Hal Jeffries watches the apartments across his courtyard while confined to his room. Mrs. Thorwald's disappearance and her husband's behavior make him suspect murder. He asks his acquaintance Boyne, a homicide detective, to investigate, but the initial inquiries appear to support Thorwald's account. Jeffries uses his helper Sam to disturb Thorwald's apartment and telephones the suspect, hoping his reactions will reveal a hidden body. Thorwald identifies the watcher and crosses the courtyard to silence him. Boyne's intervention saves Jeffries, and the investigation exposes how the apparent evidence of Mrs. Thorwald's survival was arranged.

Thorwald cuts Jeffries's telephone connection and attacks him. Jeffries uses a bust to draw his gunfire, and Boyne arrives, then shoots Thorwald as he tries to escape across the building. Jeffries realizes Mrs. Thorwald's body is hidden in fresh cement in the apartment above. Boyne confirms that the woman claiming to be Mrs. Thorwald elsewhere was an accomplice. The doctor then arrives to remove Jeffries's cast, explaining the confinement that made him rely on observation and other people's help.

Key turning points
