The planet Zarkass is a vivid wasteland of strange alien flora and fauna settled by a colonial trading post run by the matriarchal Terran forces. Threatened by mysterious triangular warships, two Terran agents are sent into the jungle under the guise of “ecological study,” but are in fact after the wreckage of one of the triangular ships. These two agents are as dissimilar as they are incompatible: Louis, a delicate and refined scientific officer, and her security escort, Marcel, a scrapper as tough they come.
