Death in Space on AllMovie

Warning, Will Robinson! The "death in space" referred to in the title may have been suicide, or may have been murder. The crew of an orbiting space capsule must get to the bottom of things when their commanding officer vanishes during a space walk. If murder is indeed the verdict, then there's only a limited number of suspects to choose from (it's not likely to have been an outside job). George Maharis, Cameron Mitchell and former child star Margaret O'Brien head the cast of this videotaped ABC Wide World Mystery presentation.
