In this made-for-TV movie, Joe (Robert Reed) and Mary have lost several children, but give it one more try. This time their newborn's immune system isn't lethal, but the child is forced to spend his life inside a plastic bubble; any contact with the germ-laden world will bring certain death. As a teen, Todd (John Travolta) suffers typical teenage angst, coupled with his growing frustration at being confined to his plastic home. He goes to high school via closed circuit TV before devising a space suit contraption that allows him to physically attend class. He also falls for Gina, the girl next door. Initially, Gina treats Todd cruelly and uses him to cheat on school tests, but eventually, she returns his affection. Todd's growing frustration leads him to risk his life by venturing out into the world, unprotected.
