Storyline

In the early 1960's, as a U.S. Navy ship cruises near Guadalcanal in the South Pacific, its sonar detects muted hammering on metal undersea. The eerie sounds emanate from a submarine on the ocean floor, maybe there since World War II. A very nervous crew member (Mike Kellin) on the ship served aboard that sub - and he was its sole survivor. Written by David Stevens

Trivia

A fathom originally was measured by a man's outstretched arms, and was later standardized as 6 feet in the universal English system. Therefore the title translates as "The 180-foot Grave." See more »

Goofs

There is a belief that the U.S. Navy stopped using the Copper Hard Hat diving helmet by 1962. When in fact, the Mark V hard hat was used by the US Navy from 1916 till 1984. In 1984 The older copper hard hat was replaced by a fiberglass version that continues to this day. There are many jobs that Navy divers perform that a diver with SCUBA gear could not perform. The heavy diving apparatus allows a diver to walk and work in higher currents without the fatigue that affect a SCUBA diver. See more »

Second episode in the newly imposed hour-long format is a prime example of its limitations: Story involves a U.S. Navy destroyer in the South Pacific that makes sonar contact with a long-sunken submarine that seems to have an inexplicable hammering come from inside it. This news greatly troubles Chief Bell(played by Mike Kellin) who it turns out was the sole survivor from that sub back in World War II, but he has a secret that he may literally take to that thirty-fathom grave... Costars Simon Oakland as the Captain, and an early appearance by future star Bill Bixby("The Incredible Hulk") Plot has a great deal of potential, but is hurt by obvious padding like too much exposition about what could be down there. Still, this succeeds as an eerie ghost story, with fine acting, but at 25 minutes, would have been a classic...
