The Maquis Part I, DS9 2
The fine print of the Cardassian-Federation treaty is causing nothing but trouble for various colonists along the border. Touched upon during the recent TNG episode Journey’s End, we get into the real nitty gritty here. Turns out there are double-dealing factions among the Cardassians (not so surprising) but there’s even a band of renegade wildcatting outlaws among the Federation!
And this is the precise moment that some hardcore Trekkies said goodbye to DS9 forever. Some could never accept that there would be a schizm in the UFP; that Starfleet would have dissenting “freedom fighters”. More on this in the (even better) Part II.
