Sub Down Film Poster


The nuclear attack submarine US Portland is on manoeuvres beneath the South Pole, with three research scientists trailing in their wake in a submersible. An accidental collision with a Russian sub sends the Portland careering to the bottom of the sea, where it lays incapacitated, its nuclear reactor in danger of leaking. The fate of the crew and the surrounding environment alike hangs on the actions of the scientists, whose small craft remains seaworthy, but they are racing against the clock: the sub only has four hours of oxygen remaining.
