Lorenzo Smythe, the excellent yet unemployed actor, meets Dak Broadbent in a bar on the Moon. Broadbent hires Lorenzo for an unspecified role, but Broadbent turns out to be an assistant to the famous interplanetary politician and leader of the Expansionist party: John J. Bonforte. Bonforte, however, has been kidnapped by the political opposition on Mars, and due to Lorenzo’s physical similarity to Bonforte, his staff wants Lorenzo to impersonate the politician for an important Martian ceremony.
