A group of soldiers are sent to hunt an out of control killer robot; however, the group start to suspect that members of the team are robots themselves.
A magnetic ore brought back from Alfa 177 causes a beam break-up in the transporter, splitting Captain Kirk into two different beings: one "good" and one "evil." The malfunction must be repaired before Sulu's stranded landing party freezes to death, and Kirk's separated "halves" perish. The Remastered edition enhances the special effects with some surprises in this landmark show.
