Abbi Hope Goldstein is photographed as a baby on September 11, 2001, holding a red balloon with a collapsing South Tower of the World Trade Center in the background. She became an internet meme, but now, fifteen years later, Abbi just wants to have a normal, unrecognized summer as a counselor at Knight's Day Camp. Unfortunately, Noah Stern, whose own life was changed forever after 9/11, comes to the camp too, and recognizes her, threatening to reveal her identity.
