DS9 S3E01 - The Search, Part I

After the chaotic and bloody introduction to the Dominion and the Jem'Hadar last season, Starfleet is doing what it does best, attempting to broker a solution. Taking a page from the book of the best defense being a strong offense, Starfleet gives the experimental USS Defiant to Commander Sisko, complete with a Romulan cloaking device. They charge into the Gamma Quadrant to find the mysterious Founders.
