富有的亚特兰大篮球队老板Raymond Armstead（Lance Henrikson饰）正在与离婚的Barbara Collins（Joanne Nail饰）约会，并似乎爱上了她，但他实际上是一个神秘的富豪集团的任务，该集团试图通过芭芭拉子宫中携带的外星基因力量的邪恶操纵来获得权力。Raymond和Collins十几岁的女儿Katie（Paige Conner饰）都希望结婚并生下一个新的孩子，这个孩子承载着Katie开始展现的力量。一个年长的男人从另一个世界出现（约翰·休斯顿饰），并作为这种力量潜在的善的力量进行干预，试图阻止凯蒂利用她的力量作恶，并将她带回一个孩子们善良的地方。
Wealthy Atlanta basketball team owner Raymond Armstead (Lance Henrikson) is dating divorcée Barbara Collins (Joanne Nail) and seemingly in love with her, but he is really on assignment for a mysterious syndicate of rich men trying to gain power through the evil manipulation of a genetic alien force that is carried in Barbara's womb. Both Raymond and the smart-mouthed and uncannily talented pre-teen daughter of Collins, Katie (Paige Conner), want marriage and a new baby to be born, with this baby carrying forth the power that Katie is starting to show. An older man appears from another world (John Houston) and intervenes as the force of good that this power potentially has, trying to stop Katie from using her powers for evil and to take her back to a place where the goodness of children can thrive.
