In Tides of War, Frank Hably (Adrian Paul) is a Navy submarine commander whose lover is his Executive Officer (Mike Doyle). Leaving aside that this might not show great judgement, the sub is on patrol near North Korea when it’s attacked by an unidentified stealth sub, killing the Executive Officer. After facing an inquiry and fearing court martial (not for being gay, just for almost getting his boat sunk), Hably is brought back to command a secret mission with a new Executive Officer (Matthew St. Patrick, of Six Feet Under fame) who’s watching his every move. Vindication arrives in the form of another sneak attack. Kent McCord and Matt Battaglia also have roles.
I’d about given up on ever finding a copy of this when I stumbled on an offer in another DVD for a free promotional copy from Here! TV.
