The Black Hole

USS Palomino is returning to Earth after exploring deep space. The crew discovers a black hole in space with a spaceship nearby. The ship is identified as the long-lost USS Cygnus, the ship McCrae's father served aboard when it went missing. A crew of faceless, black-robed android drones are in fact the human crew, who mutinied and had been lobotomized by Dr. Hans Reinhardt.
