In-Universe:
The Dominion fleet continue their attack on the U.S.S. Defiant and the rest of the helpless Alpha quadrant fleet.
Production:
This is the third version of the CGI Defiant from Digital Muse. The most telling visual element to me is the front deflector. It's supposed to be a smooth consistent curve, but in this version the top is more flat and then there is a definite 'bend' and then it curves.
