John, Stephen and Elizabeth decide to try to re-capture the Damocles. Lee Wan tells them of a dead man's switch that can launch nuclear missiles held aboard the station. John takes Lee Wan's space suit, and floats past the Damocles, pretending to be the dead astronaut. Looking through an observation port, he sees that the dead man�s switch is in use. The Doomsday Men transmit their demands to the United Nations, who postpone the signing of the peace treaty. Meanwhile, Stephen and the boys at the school go on a cross-country run. While Tim matches the voice from the Damocles with that of General McLelland, Stephen sees Douglas being kidnapped. He tries to help, but is knocked unconscious. (thetvdb.com)
