Lisa protests the building of a shopping mall on sacred ground. Her protest gets the school the ability to conduct an archaeological dig. Lisa's digging reveals a human skeleton that has wings. All Springfield is convinced it is an angel and Homer cashes in; however, Lisa is skeptical. The skeleton disappears and when it reappears it carries a foreboding message about the end of the world. As sundown approaches, the townspeople grow concerned and frightened, but nothing catastrophic happens. The skeleton floats down below the valley to a new discount shopping mall ("the end is near ... for high prices!"). Lisa figures out the whole "end is near" saga was a publicity stunt staged by the developers, not so much to not tip off would-be competitors but, as she angrily states, a way to prey on the beliefs and fears of the guillible. She calls for a boycott of the mall, but the bargain-hunting public immediately go shopping instead.
