Movie title: Impostor Context: Gary Sinise plays Spencer Olham, a top-secret government weapons designer who is arrested by a clandestine government organization on suspicion of being a clone created by the hostile alien race wanting to take over Earth. He learns from the group's leader, Major Hathaway (Vincent D'Onofrio) that the clones are perfect copies of the original human specimen (complete with memories), except they carry within their chest a small nuclear bomb, which cannot be detected without opening up the chest of the individual, in effect, killing them. The organization captured an alien transmission that stated that Oldham's clone was to assassinate the chancellor (Lindsay Crouse) when he came into contact with her, but Olham defends his humanity.He manages to escape the interrogation room and has various adventures on the lam until Olham and his wife (Madeleine Stowe) are trapped by government troops in a forest near an alien crash site. When one half of the cockpit is pulled away, revealing the murdered corpse of Olham's real wife, the government troops turn their guns on the surprised clone to prevent her bomb from detonating. However, when the other half of the cockpit is pulled back, revealing Olham's corpse, the other Olham finally realizes he was indeed the clone the government thought he was. The words he utters on seeing the real Oldham's corpse causes the detonation sequence to engage. Hathaway turns around at the last moment to see Oldham's eyes turn black and the bomb in his chest explode, destroying everything within several miles and claiming the lives of thousands of people.
