STAR TREK: DEEP SPACE NINES1, E18
Dramatis Personae
Acting out roles both melodramatic and deadly, the DS9 staff is infected by a viral historical incident archive from an alien culture within the Gamma Quadrant. The Klingon crew that unwittingly brought the virus killed itself in paranoid anarchy, and DS9's crew seems headed the same way unless Odo can stave off the madness.
