Merriwether lives his false reputation as a great white hunter to the point of living in a Manhattan apartment furnished to look like an African safari lodge complete with sound effects records of African fauna. Based on his false reputation as an "Africa Expert", he is recruited by the United States Government and NASA to locate a missing secret Unmanned space mission before it can be located by hostile forces.
