Almost 10 years ago I saw an English sci-fi film on a Hungarian TV channel.
The story was about a military mission started from Earth to an alien planet to destroy the whole race. The full story was happen on the same starship (mainly the conversations and the mood of the film was interesting). The leaders of the mission has only one eye, because one of their eye was exchanged to a special monocular computer interface. This interface was used to unlock secret codes.
On the way to the alien planet some type of malfunction happened, and also some solder died. Step by step more army man died, and at near to the end of film just a few people remained. They feel the mission in danger and tried to save the situation. Finally only one young solder remained alive who launched the nuclear bomb carried by the starship to destroy the planet where the ship arrived. Unfortunately the ship is arrived to the Earth, because one alien lived with them on the ship and she reversed the ship at the middle of their travel.
This enemy alien was looks like a normal man, because the aliens make surgical operations on one of their female specimen, and convert her to human like creature.
Does anybody know the title of this film?
