A young lieutenant named Ilario is found dead in his quarters. An investigation reveals he was shot by a TR-116 rifle, a weapon developed but never mass-produced by Starfleet. Meanwhile, Ezri confronts one of Dax's previous incarnations in a dream: Joran, a self-professed murderer, urges Ezri to channel his disturbing memories and enable him to assist her in apprehending Ilario's killer. When Ezri awakens, she learns that a second murder has occurred.
