What they find however is a crashed spaceship of Earth design. Inside the ship they three dead crew members - but the dead are their duplicates and the crashed vessel is the E81. The captain refuses to accept that they might be dead and explores several possibilities to explain what has happened including the theory that they may have time-traveled.
