Stardate not given: O'Brien accidentally triggers an automatic
security program in one of the defunct ore processing
plants. The pre-programmed subroutine was programmed
by Gul Dukat to halt any uprising by the Bajoran
slave workers years ago, but its countermeasures are
still potent, ranging from force fields and bulkheads
to deadly gas. When these obstacles are thwarted by
the crew, "Dukat" has an ace up his sleeve:
the station's self destruct routine. Dax discovers that only Gul Dukat himself
can abort this program. It just happens that Dukat
has learned of the situation aboard the station and
has decided to pay a visit so he can gloat over Kira. But when he tries to leave DS9 to its fate, he finds that his
superiors predicted that Dukat would try to flee the
situation, and he too is trapped on the doomed
station.
