Bernard Walton is cleaning the windows at Madge's shop when Wooton notices an odd mark in the glass. It resembles the special symbol Power Boy uses to summon help in the comic books. Bernard assumes someone has played a prank, but the mark appears only when he sprays on Howard Chastiderwitz's new no-streak, no-glare window cleaner.
The same symbol appears on four newly installed windows Bernard has cleaned. Since Wooton has seen each mark, Bernard briefly suspects him, but Wooton insists that he has not caused them. Bernard tries to dismiss the mystery and returns to work, only to discover another new window at Whit's End bearing the same hidden sign.
Whit and Connie help Bernard compare the affected windows. They tie the affected windows to a sales offer taken up about a month earlier - Whit's End had replaced its front window under the same deal - though the supplier's name comes out only as a half-remembered “Seymour or Seeshine.” Howard's cleaner is the other link. Bernard and Wooton decide to visit Wayne Chemical Company, where Howard works, while Whit and Connie continue searching for information.
At the laboratory, Howard explains that his cleaner changes the way light reflects from glass. When Howard sprays it on a Seawright test pane, the Power Boy symbol appears again. The discovery proves that the mark is already inside or beneath the surface of the glass, though no one yet knows who put it there. Howard, another devoted Power Boy fan, becomes so excited by the mystery that he has to stop and catch his breath.
Back at Whit's End, Connie tries an unusually direct Internet search and finds a newspaper photograph from Greensburg. The same symbol has been painted on a wall there. Whit and Connie trace it to a protest against the labor practices of Seawright Window Manufacturing. Protesters are using Power Boy's call for help to draw attention to their cause.
When everyone compares discoveries, Whit explains that a Seawright vice president, Mr. Corelli, blames the protest on a bitter former employee. Corelli offers to replace every damaged window at no cost and asks Bernard to contact him. Bernard is relieved that the company seems ready to solve his customers' problem.
Wooton is not satisfied. To him, the symbol is more than graffiti or a manufacturing mistake. Someone chose a sign that means a person is in serious trouble, and he believes that plea deserves an answer. Though the others think the mystery has reached a simple conclusion, Wooton announces that he is going to Greensburg to learn who needs help - and why.
