When Diane Schwebe, director of a major New York museum, is awakened by a text from the museum's lawyer, it is the start of a twenty-four-hour roller-coaster ride. Diane has sacrificed many things to help the fading institution stave off financial ruin. In this battle, she's surrounded by her stalwart supporters: her personal assistant, Chris; the museum's head of security, Shay; and its general counsel, Henry - a man whose ability to weasel his way out of a jam is matched only by his capacity to avoid learning anything from the experience. On this day of the museum's annual gala, every plate Diane has kept spinning will fall and by daybreak someone will be dead.
