An expatriate American (Ivan Dixon) living in Africa must regain his citizenship before enemy agents kill him.

An agent is condemned as a turncoat pleads with pal Robinson to spare him and help undo the damage.

An aged Chinese-American merchant (Philip Ahn) asks the partners to deliver his back taxes to the U.S. government so he can die with honor.

Robinson and Scott must help a confused counterspy retrieve stolen papers before the error becomes fatal.

The agents are alarmed when the person involved in their top priority assignment is apparently poisoned.

Captors demand heroin as ransom for Scott, held in a nightclub performer's dressing room.
