Gul Dulcet, the Cardassian commander, and a protege of Gul Dukat, has plans for Garak and no use for Bashir, Sisko, and the Maquis. Injured trying to help a wounded prisoner, Bashir finds himself in the infirmary where he learns that Tessa is a doctor and has cooperated with the Cardassians because they have promised to release her brother, a member of Chakotay's Maquis crew, whom the Cardassians claim to have captured. Bashir escapes and frees the others, just as Kira arrives in the Defiant. Dulcet and Tessa escape. Tessa discovers she has made a fatal mistake, and Dulcet learns that trusting Dukat may have fatal consequences as well.
