Odo is in his office, eagerly awaiting his weekly meeting with Major Kira to review criminal activity on the station. The meeting is interrupted by Quark, who complains on how Odo practicing shape-shifting in his quarters (right above Quark's own) causes too much noise. Odo orders Quark out of the office while confessing to Kira that it's no accident his quarters are right over Quark's. Later, the crew welcome First Minister Shakaar, visiting the station to push for Bajor's early admittance to the Federation. Odo breaks in to warn them that a threat has been made on Shakaar's life, courtesy of the True Way, a Cardassian terrorist group who have already killed two Bajoran officials. Shakaar refuses to end his visit but agrees to extra security with Worf aiding Odo. The Klingon and the Changeling have a discussion where both find common ground in disliking unwelcome guests and interruptions to their ordered routine.

At first, Odo and Shakaar get along well, sharing their concerns over the Federation's self-righteous attitude. However, Odo soon sees the bond between Kira and Shakaar and is struck when Shakaar admits he's falling in love with Kira. While doing a security sweep of a conference room, Odo finds a listening device and accuses Quark of planting it. Quark responds by noting how he knows Odo is in love with Kira and worried about Shakaar which Odo denies. Kira is forced to call off a meeting with Odo to be with Shakaar, the two almost kissing. As they take a turbolift, Odo hears the two talking about plans for the evening. When Worf's voice asks to take control of the turbo-lift, a distracted Odo grants it without asking for the security code. The turbo-lift begins plummeting but Odo changes his arms to solid pylons to stop its descent. Odo relates to Sisko that the True Way agent imitated Worf's voice to take control of the turbo-lift, admitting he failed to hear Worf's code. Sisko is surprised at Odo's mistake ("To err is human but you're not human, constable. You're not even humanoid.") and warns him not to let it happen again. Odo's mood worsens when he goes to see Kira, who admits that she and Shakaar are now in a relationship and Odo is unable to tell her his feelings. Even worse, when he returns to his office, Odo discovers that Worf has arrested the True Way operative, captured after attempting to sabotage the environmental controls of Shakaar's quarters.
