The Andromeda Strain is a deadly extraterrestrial virus. It is brought to Earth when a research satellite crashes near a tiny Arizona town. Everyone in the community dies within days, except for a baby and an insulated drunkard.
Recruited from labs all over North America, doctors Charles Dutton (David Wayne), Jeremy Stone (Arthur Hill), Ruth Leavitt (Kate Reid), and Mark Hall (James Olson) don radiation suits and race against time to isolate and destroy the virus. The film is based on a novel by Michael Crichton.
