The country of Santales sold a collection of Incan gold artifacts to save its economy, which were stolen by Jack Cole. Cole's accomplices are killed and Colonel Cardoza of Santales is in charge of extracting the location of the artifacts from Cole. However, Cardoza is a tratiro who plans to take the artifacts and leave Santales in financial ruin. The IMF must both recover the treasure and expose Cardoza. Phelps goes in as Cardoza's fence, and plots with the Colonel to get Cole to reveal the treasure. Phelps is thrown in with Cole, and they manage to escape thanks to Cardoza's set-up with Jim. Jim ""kills"" Rollin (disguised as an Indian) for his horses, and the Rollin reports to Cardoza's superior, General Diaz, that Cardoza is the one looking for the trasure. Cole takes Phelps and Cardoza to the trasure, and Cardoza kills Cole. As Diaz's men close in, Jim leaves via a helicopter, leaving Cardoza to try and explain why he has the treasure and was working with Cole.

Riva Santel is the recent widow of the President of San Cordova. Deputy Premier Avilla plans to announce free elections but Riva will declare herself dictator in a coup. The IMF must stop her. Pretending to be a film crew, the IMF team gets in. Hostess Cinnamon fakes a collapse and the guys comment on her age. Rollin as a plastic surgeon comes in and Riva finds out Cinnamon is actually seventy years old. She insists on surgery for herself. Since the surgery can only be done on the night of the speech, she has herself taped by her own camera crew. Barney and Willy get hold of the tape footage, reedit it, and switch the IMF tape for Riva's. Riva is sedated during the speech and so her men use the tape. When she awakens, her face in bandages, she is shocked to hear ""herself"" announcing her retirement. While Cinnamon disguised as old-Riva conspicuously leaves the country, Riva takes off the bandages to find she has her wish: she is now a younger woman...with a totally different face.
