Below the Surface

A gripping tale of deception and desperation unfolds in "Below the Surface", a 1920 American silent drama film directed by Irvin Willat. The story follows Martin Flint, a respected deep-sea diver, who is enticed into a phony scheme to recover gold from sunken ships, but refuses - forcing his son Paul, and even his own daughter-in-law Edna, to be manipulated into helping the con artists. When all else fails, Martin's determination to save those he loves puts him in a life-or-death situation, as he battles against overwhelming odds to rescue his son and daughter-in-law from a treacherous underwater grave.
