A Cardassian military leader arrives on DS9 as a guest and an assassination attempt follows. Odo captures a Starfleet lieutenant running from the scene, whom O'Brien recognizes as Ro Laren. Ro escapes and a manhunt ensues. She remains one step ahead of station security until O'Brien captures her, but she insists that they are working on the same side, to prevent the assissination and the destruction of the station. O'Brien reluctantly follows Ro. When they find and subdue the real culprit, O'Brien does nothing to prevent Ro's escape.
