Race-car driver Blaine Striker grows concerned about his younger brother, a student at a medical school on the Caribbean island of St. Heron. General Turner has led a violent coup on this island and may be planning to blow up the school in order to blame the destruction on counterrevolutionaries. Striker infiltrates St. Heron, is captured, stripped to his tighty-whiteys, and electrotortured. He escapes, joins forces with the counterrevolutionaries, and foils a plot to assemble Russian missiles on the island.
Xixo is back again. This time, his children accidentally stow away on a fast-moving poachers' truck, unable to get off, and Xixo sets out to rescue them. Along the way, he encounters a couple of soldiers trying to capture each other and a pilot and passenger of a small plane, who are each having a few problems of their own.
