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 spell-binding 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-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. Back on Earth, Charles Keith (Academy Award-Winner Gregory Peck - Best Actor in a Leading Role, To Kill A Mockingbird, 1962), chief of the manned space program, and senior astronaut Ted Dougherty (David Janssen) plan an incredible rescue - while the whole world waits anxiously.
