Their search for an Easter Island idol takes the Hardy boys to Easter Island and on to investigate the theft of government material in Antarctica.

The Hardy boys dial a wrong number, get the Pentagon, and suddenly find themselves in a dangerous adventure involving national security.

Frank and Joe uncover a coded message that points to big trouble in the local circus. Someone in the circus wants to make the boys disappear permanently.

Caught in their motorboat the "Sleuth", by a sudden storm at sea, Frank and Joe are helpless when the engine conks out. Drifting farther from shore amid the tumultuous waves, the boys are relieved to see the lights of a yacht. But their SOS is ignored.
