The film centers on the life of Tod Lubitch, who was born with an improperly functioning immune system. This means that contact with unfiltered air may kill him, so he must live out his life in incubatorlike conditions. He lives with his parents, in Houston, Texas. He is restricted to staying in his room all his life, where he eats, learns, reads, and exercises, while being protected from the outside world by various coverings.As Tod grows, he wishes to see more of the outside world and meet regular people his age. He is enrolled at the local school after being equipped with suitable protective clothing, similar in style to a space suit. He falls in love with his next door neighbor, Gina Biggs, and he must decide between following his heart and facing nearcertain death, or remaining in his protective bubble forever. In the end, after having a discussion with his doctor who tells him he has built up some immunities which may possibly be enough to survive the real world, he steps outside his house, unprotected, and he and Gina ride off on her horse. ........
