Dr. Bashir, scheduled to leave for a conference the next day, tends to Chief O'Brien, who has dislocated his shoulder while kayaking in a holosuite. Bashir wakes up the next morning feeling tired, and is summoned to a meeting of the senior staff. Sisko introduces Sloan, the deputy director of Starfleet Internal Affairs. Sloan suspects one of them of being a Dominion spy, and they are confined to quarters.

Bashir finds his replicator out of order. He is escorted by a security detail to the ward room. Sloan treats him cordially while asking a few light questions and seems satisfied. He explains that the replicators have been disabled as a security measure, and takes Bashir's breakfast order for scones, so it can be brought to him (Sloan's man delivers him Worf's breakfast of Gagh instead of Bashir's scones). Upon returning to his quarters, Bashir suspects they have been searched. O'Brien secretly contacts him on a monitor, warning him that he was interrogated for hours, with every question about Bashir.

Bashir is then brought back to Sloan, who has changed his tone. He accuses Bashir of being a traitor, pointing out his subversive attitude, including his sympathy for renegade Jem'Hadar trying to cure their Ketracel White addiction ("Hippocratic Oath"), lifelong dishonesty about his genetic enhancements ("Doctor Bashir, I Presume?"), and agreement with a group of savants who suggested the Federation's best course of action was surrender ("Statistical Probabilities").
