After Mr. Burns is caught storing his excess nuclear waste inside Springfield Park's trees, he is ordered to pay the town $3 million.

The town embraces the suggestion and Homer is hired as the conductor, but the only person remaining not so pleased about the whole situation is Marge. She discovers suspicious evidence and visits a town that had previously purchased one of Lanley's monorails. She discovers that Lanley is indeed a con man and rushes back to town. However, she arrives too late and the monorail has begun to operate, but Homer is convinced to use an anchor to stop the train, thus saving the passengers.
