Stardate not given: Sisko is
kidnapped by O'Brien's counterpart from the parallel timeline
visited by Kira and Bashir a year before, and is cornered into
assuming the role of his violent, lascivious
alter-ego who has died while fighting for the Terran
rebellion against the Klingon-Cardassian Alliance.
His mission - to get aboard Terok Nor and contact
turncoat human scientist Jennifer Sisko before she
can develop a new sensor array that will mean the end
of the rebellion. Though his fellow rebels feel
Jennifer could be assassinated as easily as she could
be liberated, Sisko must
do everything he can to keep the alternate timeline
incarnation of his wife alive while not betraying the
rebellion.
