Sub Down(1997)

Sub Down is a survival thriller that follows two research scientists racing against time to rescue a nuclear attack submarine and its crew after it crashes on the Arctic ocean floor. With oxygen running dangerously low and the clock ticking, the pair must navigate the treacherous conditions of the deep sea to prevent a catastrophe. The film combines high-stakes tension with the claustrophobic horror of being trapped beneath miles of ice and water, as the scientists work to mount a desperate rescue operation. Every decision carries weight as they confront both the technical challenges of deep-sea recovery and the human cost of failure.
