They are trapped in a spaceship with no power. Outside there is no air and no heat. Earth spins 200 miles below. Three astronauts face a desperate situation in this spellbinding science fiction cliffhanger. After completing a daring mission in space, the three-man spaceship Ironman One orbits Earth preparing for re-entry. But a retro-rocket misfires, and the crew commander Jim Pruett (Richard Crenna), scientist/astronaut Clayton Stone (James Franciscus) and pilot Buzz Lloyd (Academy Award(r) Winner Gene Hackman Best Actor in a Supporting Role, Unforgiven, 1992; and Best Actor in a Leading Role, The French Connection, 1971) are marooned in space.
