Arthur and Buster trick D.W. into thinking that the big, green potato chip she ate was poisonous. Rather than admit to eating it, D.W becomes friends with Binky, who had eaten one as well. Believing he is close to death, Binky is motivated to reveal his private passion of ballet, impressing his friends. When the story of D.W. believing a green potato chip is poison (from the previous episode) becomes a story in the newspaper, she promptly blames Arthur for telling about it. D.W. finds out that her mother is the one telling people about the story, and tells her how upsetting it is. Mrs. Read apologizes and promises not to repeat the story. D.W., in turn, apologizes to Arthur, who invites D.W. to a live show where Binky performs a ballet about his experience with eating a green chip. However, while waiting in line for the show to start, D.W. overhears her mother talking to Mrs. MacGrady about the newspaper article. D.W. runs to a nearby pier, where Binky is warming up for the ballet. Mrs. Read explains to D.W. why she was talking about the story. They reconcile and Mrs. Read agrees to not discuss the green chip article to protect her daughter. Arthur, D.W., and their mother enjoy Binky's ballet.
