A NASA satellite with a TV camera, accidentally lands on the island instead of the intended target: Mars. The castaways try to communicate their S.O.S. when the camera is operational.

Gilligan has the winning ticket for a South American sweepstakes.

The Professor thinks that the island is sinking, which causes the Castaways to panic. As it turns out, Gilligan has mistakenly moved the Professor's measuring stick, so the panic was a false alarm.

Gilligan discovers an island bush that produces seeds which, when eaten, give a person the ability to read the minds of others. This leads to disaster when everyone insults each other through their honesty and thoughts.

The Howells plan a party, and Mr. Howell accidentally loses the Skipper's invitation. The others refuse to attend, believing that the Howells have intentionally snubbed the Skipper.

Hot water spurting from beneath the island pleases the castaways as they can now have hot water piped to their huts. However, the hot water also concerns the professor since it means that increased volcanic activity may be imminent. The Professor saves the day by making a bomb from ingredients found on the island (of course!) to spike the volcano.

The radio reports that Mr. Howell has been rescued and is spending all of his money. Obviously, there is an imposter! The real Mr. Howell is frantic, and offers a reward to the person who can come up with a plan to get him back to civilization.

There the imposter conks Mr. Howell on the head with a coconut, changes clothes with him, and attempts to continue his masquerade as the millionaire.

A radio bulletin states that the minister who married Thurston and Lovey Howell (the Reverend Buckley Norris of Boston) was a fraud, and that the Howell's marriage is actually null and void.

In the end, it turns out that the radio announcer was at fault: While he mistakenly reported that "Buckley Norris" was the fraudulent minister, he was supposed to say "Borris Nuckley."

A huge meteor lands on the island, causing everything nearby to age very rapidly. The Professor determines the rapid aging is being caused by strong cosmic rays (he makes this determination by using his bamboo Geiger counter!).
