Matthew Handy invents a light bulb that uses less energy. The energy consumption is seven times less than of a conventional incandescent light bulb. His neighbor, John Stickyfingers, offers space in his store to sell the invention. Naively, Matthew accepts the proposal from John without knowing that he intends to offer the manufacturing contract to Darkhand. In Darkhand's laboratory they will manipulate Matthew's invention so that it works opposite of Matthew's intention: when the light bulb is turned it will consume much more energy than a regular light bulb, which will benefit the Putrefaction company. The neighbors begin to complain about the increase in their bills, accusing of Matthew of having invented a faulty light bulb. In the end, the light bulb causes an electric blackout in the city. Matthew resolves the problem, but Darkhand has to admit, finally, his part in the scheme.
