Duet

A Cardassian named Marritza arrives on Deep Space Nine suffering from Kalla-Nohra Syndrome. Major Kira immediately suspects that there is more to Marritza's story that he claims there to be. She has him locked up and then interrogates him while Odo finds out what he can about Marritza's past.

Evidence comes to light that makes it look like Marritza is lying about his identity. The real Marritza was a file clerk at Gallitep, a forced labor camp on Bajor run by the Cardassians. Before the investigation into Marritza's past is concluded it seems that Marritza is actually Gul Darhe'el, the former commander of Gallitep.

The Cardassian being held on Deep Space Nine admits that he is Gul Darhe'el and that Marritza is dead. Something still doesn't seem to be quite right, although Kira is more than satisfied with Gul Darhe'el's statement as to his identity.
