9/10 tells four interwoven multicultural stories that take place in the World Trade Center on the night before September 11, 2001.

How does it feel to watch a group of people go about their ordinary lives when you know that in less than twenty-four hours their world will change? Roberto, a young Dominican-American elevator man, is pestered by Walter, an older Black security guard, to turn down his loud music, until Roberto reveals he’s trying to mask the sound of a woman he's convinced he hears crying in the elevator shaft. During a party at Windows on the World, Colin, a young firefighter, nervously anticipates proposing to his girlfriend Allison, who beats him to the punch by announcing that she never wants to get married, and whose obsession with events that occurred just prior to the Titanic sinking presages her own fate. Working overtime, Scott, a lonely gay account executive, ends up in an unlikely bond with Sahar, a devout young Muslim woman who's temping the graveyard shift and husband-hunting online in her spare time. And in an empty office, Grace, a tall white actress, and Roy, a shorter Asian actor, running lines for an ill-fated Equity showcase of Barefoot in the Park, teeter on the brink of career suicide -- and an unlikely middle-aged romance. In the course of 9/10, it is revealed in sometimes surprising ways that some of these people will be in the towers the following morning, but the play is as much an elegy to an almost-forgotten New York City as it is about the devastation of 9/11. The dreams the city has always inspired -- in everyone from Roberto’s Dominican uncle, to Trade Center architect Minoru Yamasaki (Roy's hero), to playwright Neil Simon, to a woman who was hurt falling in the subway the day before the Titanic sank -- are an integral part of the script, as is the enduring voice of those dreams, which survived September 11.
