It is the mid-1970s. The Summer of Love and the Woodstock Music Festival have come and gone. Into the atmosphere of cynicism and doubt following the wild optimism of the youth revolution the Love Children, raised from birth by benevolent aliens, come home to Earth. Sexually free, telepathic and honest to the extreme, they are appalled to find that the world they left behind is full of darkness and deceit. As they set about using their extraordinary powers to bring light and unity back to their world, they run up against a sinister alien force intending to keep it in darkness.
