Finriddy and Carson are two explorers sent to survey the planet Boohte. Back home, breathless fans follow their adventures: in reality, they deal with dust, nit-picking regulations, and uncooperative aliens. Teamed with a young intern whose specialty is mating customs and a native guide of indeterminate gender, the group sets out for a previously unexplored sector of the planet -- but they soon find themselves in alien territory of another kind: exploring the paths and precipices of sex. And love.
