When a cab driver picks up his next fare... he takes a journey into his past and learns his future: Susan gets into a waiting cab when she realizes that Nathan is the driver. She asks to 'know how it happened, that she deserves to know.' Nathan tells the story of American Soldiers exchanging rounds with Al Qadia as the sequence goes to FLASH BACK... when Rich is shot. The soldiers carry the wounded man through a battle field to a helicopter; when the helicopter rises into the sky, Rich dies. Back in the cab, Susan tells Nathan that Rich never knew of their relationship, that she has something to show him... as she hands Nathan a photo of his Son.
