Sometimes DS9 is all about the social commentary, and sometimes it is action-adventure. This is the second.
Pretty much a classic submarine tale, with little B-stories with individual groups of characters dealing with their own crises. Jadzia and Julian trapped in a meat locker not quite as touching as Kira desperate to keep Sisko out of a coma by discussing Bajoran beliefs. Best: Quark disarming a torpedo. Very entertaining.
