One Day is a September 11 story. It is an experimental documentary dealing with the events of the September 11, 2001 tragedy in New York City. One Day is a filmmaker’s dialogue about visiting New York City before and after the disaster, with footage taken years ago in the World Trade Center, at the end of September 2001, and in January 2002. One Day is also a portrait of two New Yorkers exploring lower Manhattan and viewing the burning ruins, speaking of their feelings about the event, and attending a public memorial by a Navajo spiritual leader.
