"Depth Charge" focuses on veteran naval Commander Krieg (Eric Roberts), who has commandeered his own submarine with the help of mercenaries. While demanding a ransom in exchange for sparing the lives of billions from a nuclear attack, Commander Kreig is unaware that saboteurs are bent on stopping him from carrying out his dangerous and destructive plan. On board are two of the submarine's original crew and they will do anything they can to stop the madman. A standoff begins fathoms below sea level, with the fate of the world at stake. There are elements here of "The Caine Mutiny" (Capt. Queeg, Commander Krieg) and "The Hunt for Red October," with lots of action and a fast pace. Special effects, however, are not convincing.
