Two genetically engineered beings unexpectedly arrive on Earth. Unlike most extraterrestrials depicted in science fiction, the pair is attractive, personable, and telegenic-the perfect talk show guests. They have come to Earth as ambassadors bringing an offer of partnership in a confederation of civilizations. Technological advances are offered as part of the partnership. But humans must learn to cooperate among themselves to join.
Molly, a young reporter, and Paul, a NASA scientist, have each suffered personal tragedy and carry emotional baggage. They are asked to tutor the ambassadors in human ways and to guide them on a worldwide goodwill tour. Molly and Paul observe as the extraterrestrials commit faux pas while experiencing human culture. They struggle trying to define a romance and partnership while dealing with burdens of the past.
However, implementing actual change is difficult for mankind. Clashing value systems and conflicts among subgroups of humanity erupt. Inevitably, rather than face difficult choices, fearmongers in the media start to blame the messengers.
