Kira is surprised when Latha Mabrin, a fellow member of her old resistance cell, is murdered during a ceremony. Her suspicions grow when she receives an untraceable message moments after learning of the murder. The message consists only of a photo of Latha and a scrambled voice saying: "That's one." Kira interprets this as a threat to all former members of the Shakaar Resistance Cell and attempts to contact the surviving members to warn them.
