Glenn Ford stars as American pilot Martin Ordway, who joins an expedition to scale a treacherous Swiss mountain peak. Each of the climbers has a special reason to reach the top. Dissolute French author Paul DeLambre (Claude Rains) is searching for a purpose in life; guide Andreas (Oscar Homolka) is doing his job; British naturalist Nicholas Radcliffe (Sir Cedric Hardwicke) hopes to uncover new forms of flora and fauna; Carla Alton (Alida Valli) wants to conquer the mountain that claimed her father's life; Ordway has fallen in love with Alton and wants to be near her; and ex-Nazi Mr. Hein (Lloyd Bridges) hopes to escape his past. As the climb progresses, each member of the party reveals his or her true character, and it isn't always pretty. Originally slated to be produced by Adrian Scott and directed by Edward Dmytrk,
The White Tower
was assigned to Sid Rogell and Ted Tetzlaff when Scott and Dmytrk were blacklisted. Another future blacklistee, Paul Jarrico, adapted his screenplay from a novel by James Ramsey Ullman.
