A newly promoted Sisko hops in the Defiant to scope out what may or may not be activity on the Tzenkethi border. But, ruh-roh, turns out there’s a Founder on board and he’s set the ship on a one-way mission to start a war! With the Federation and Tzenkethi duking it out, it’ll be that much easier for the Jem’hadar to overtake the Alpha Quadrant.
Luckily, they all saw Kurt Russell in The Thing and are able to suss the guy out.
But are they too late to prevent a different war?????
