Plot
Ten people, all strangers to each other, are invited to a small isolated island off the coast of Devon, England, by a Mr. and Mrs. Owen. They settle in at a mansion tended by two newly hired servants, Thomas and Ethel Rogers, but their hosts are absent. When the guests sit down to dinner, they notice the centerpiece, ten figurines of Indians. Thomas puts on a gramophone record, through which a man's voice accuses them all of murder:
General Sir John Mandrake, of ordering his wife's lover, a lieutenant under his command, to his death
Emily Brent, of the death of her young nephew
Dr. Edward G. Armstrong, of drunkenness which resulted in a patient dying
Prince Nikita Starloff, of killing a couple while speeding
Vera Claythorne, of murdering her sister's fiancé
Judge Francis J. Quinncannon, of being responsible for the hanging of an innocent man
Philip Lombard, of killing 21 South African tribesmen
William H. Blore, of perjury, resulting in an innocent man's death
Thomas and Ethel Rogers, of the demise of their previous employer, an invalid
It becomes apparent that none of the ten knows or has even seen "U. N. Owen"; they then realize the name stands for "unknown." They also cannot leave the island, as Rogers informs them that the boat will not return until Monday, and it is only Friday.
Starloff admits his guilt, then dies from his drink, which was poisoned. The next morning, it is discovered that Mrs. Rogers died in her sleep. The guests notice that one figurine is broken and another missing after the two deaths. With the two deaths matching the Ten Little Indians nursery rhyme, they search the island for "Mr. Owen" without success. After General Mandrake is stabbed to death, the judge declares that Owen must be one of them.
