O'Brien and Jake are examining one of the old ore processing unit to see if it can be turned into a deuterium refinery. Sisko checks up on them, just while Jake finds a strange file in the database that he can't delete. When O'Brien wants to set it apart for analyzing, he trips a Cardassian security alert. He must enter a password, but fails. Suddenly the room is locked down and a recorded message Gul Dukat appears on a view screen. He warns the 'Bajoran workers' to surrender to their superiors or face the consequences. Neurocine gas will be released. With the first option not possible, Jake finds a way out of the room through an uridium shaft. But their troubles and that of the station's are far from over. Written by Arnoud Tiele (

The station security system demanding upper level security clearances to end a revolt is a glaring error by the Cardassians - in a revolt, the death of the higher-ups would very likely be one of the first events to occur. The lack of their presence would doom a station with many Cardassians on board. See more »

A neat idea but it did seem to take a LONG time to get to the finale...
21 December 2014 | by (Bradenton, Florida) – See all my reviews

While doing some routine work on the station, a long-hidden program is activated. It seems that an old Cardassian program designed to handle rebellions by Bajoran slaves on the station was hidden in the system and has just begun broadcasting warnings from Gul Dukat. The warnings indicate unless the rebellion is stopped immediately, stern measures will result. The stern measures mean a release of poison gas! So, as the Commander and crew try to turn off the program, they need to keep moving in order to prevent from being killed. Eventually, however, the real Dukat arrives and he thinks this is all very funny. Well, by the end, the joke is on him. See this one and see what I mean.

The idea for this show is pretty novel and generally good. However, it is hard to sustain this for the entire program and eventually it becomes a bit overlong. An excellent idea but one that was difficult to sustain for so long.
