Jan Viborg, a criminal, makes a false affidavit, which causes the British authorities to revoke Sailor's visa. Slate Shannon saves his ward Sailor Duval from a frame-up. Slate needs maps to clear Sailor of theft charges. By signing a false deposition, thug Ian Vilborg frames Sailor in a theft. He tells Shannon he will retract the deposition only if he steals an aluminum company maps of Caribbean bauxite deposits. Shannon gets the maps, finds himself in a bigger jam than Sailor’s.
