The swimming pool of the Mille-Collines hotel, Kigali, in the early 1990s, draws a regular crowd of assorted aid workers, strutting Rwandan officials, Belgian businessmen, French paratroops and Canadian expats. Among them is Bernard Valcourt, a documentary filmmaker from Quebec, on a mission to set up a television station in the capital. Valcourt, who for two decades has earned his living from wars and famines, lingers around the pool drinking warm beer and watching football; but most of all, watching Gentille, a beautiful young waitress, who is a Hutu but often mistaken for a Tutsi because of her family’s strange history.
