Tom takes control of Voyager in the worst possible circumstances, and the crew under him learns to compromise their ethics to find a way to save their ship.
While I love comedy, the episodes and plotlines that really caught my interest in DS9 and Voyager were the darker ones. This story is a perfect example of some of the things Star Trek can make work very well when the writers and producers invest on the high drama potential: a threatening alien presence and a desperate crew that has to push the limits of both the regulations and their own personal ethics to save their shipmates.
