Ten people, eight strangers and two married domestics, find themselves stuck in a remote snowbound castle with no means of escape. As each of them is murdered one by one, it's a race against time to find the murderer before no one is left alive. Based on the classic mystery by Agatha Christie and directed by George Pollock. One of Christie's most popular novels, there have been many adaptations done in film, television and the stage. The most famous is Rene Clair's 1945 film version which like Christie's novel is set on a remote island. This version is rather mundane and done without any flair. If one is unfamiliar with Christie's source material, one might be taken with this version but to Christie legion of fans, it' serviceable and nothing more. Outside of Wilfrid Hyde White's performance as a judge, the rest of the cast appear to be going through the motions. The rest of the cast: Hugh O'Brian, Shirley Eaton, Fabian, Daliah Lavi, Dennis Price, Stanley Holloway, Leo Genn, Mario Adorf and Marianne Hoppe.
