Rear Window is a 1954 suspense film directed by Alfred Hitchcock, and written by John Michael Hayes, based on Cornell Woolrich's 1942 short story It Had to Be Murder. Photographer L.B. Jeffries is recuperating from a broken leg and confined to a wheelchair in his small Greenwich Village apartment. He passes the time by spying on his neighbors through his apartment's rear window, including a dancer, a lonely woman who lives by herself, a songwriter working at his piano, and several married couples, including a salesman, Lars Thorwald, with a bedridden wife. Every day Jeffries is visited by Stella, a home care nurse and Lisa Fremont, his girlfriend. He talks to both of them about his neighbors. After the salesman makes repeated late-night trips carrying a large case, Jeffries notices that the bedridden wife is now gone, and sees the salesman cleaning a large knife and handsaw. Later, the salesman ties a large packing crate with heavy rope, and has moving men haul it away. By now, Jeffries, Stella, and Lisa have concluded the missing wife has been murdered by the salesman.

When a young Amish woman and her son get caught up in the murder of an undercover narcotics agent, their savior turns out to be hardened Philadelphia Detective John Book.
