After a collision with a comet, a nearly 8km wide piece of the asteroid "Orpheus" is heading toward Earth. If it hits, it will cause an incredible catastrophe which will probably extinguish mankind. To stop the meteor, NASA wants to use the illegal nuclear weapon satellite "Hercules," but soon discovers that it doesn't have enough firepower. Their only chance to save the world is to join forces with the USSR, which has also launched such an illegal satellite. But will both governments agree?
When nuclear weapons are smuggled into America, FBI Agent Shane Daughtry (David A.R White) is faced with an impossible task -- find them before they are detonated. The clock is ticking and the only people who can help are a washed up arms dealer (Lee Majors), a converted Israeli Mossad Agent (Stacy Keach) and a by- the-book CIA Deputy Director (Randy Travis).
