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

Did You Know?


The hull number for the sunken submarine, 714, was not actually used by the Navy until the construction began on the USS NORFOLK SSN714 in August of 1979. In the episode, it was mentioned that the submarine was built in 1941. Those built in 1941 had "21x" hull numbers. See more »


There is a belief that the rank of captain determines the rank of the medical officer aboard a destroyer. In fact, all destroyers up to an including the latest (2016) Arleigh Burke class destroyers are manned by enlisted hospital corpsman. In the case of the larger Burke class, there are two corpsmen. But the smaller classes that went before, Knox class, Fletcher class, Sherman Class, etc.. All had a single enlisted hospital corpsman aboard. These corps are well trained for six months prior to being deployed. This contrasts with much shorter Army medic training. See more »

A Classic Ghost Story
21 April 2014 | by (United States) – See all my reviews

I first saw this episode about fifty years ago and when I finally watched it again, it all came back to me. This is a wonderful ghost story. It takes place aboard a Naval destroyer where strange pounding sounds are picked up on sonar. This is puzzling. They seem to be coming from a submarine, lying at the bottom of the ocean. It had been sunk twenty years earlier, yet it seems that there is someone alive in there. A diver is sent to investigate and after two tries he identifies the number. Meanwhile, another plot is going on. A career Navy man is experiencing great anxiety which is affecting his performance on the ship. He is irrational and hallucinatory. He is under psychological care. He claims to have seen a group of sailors, soaked and covered in seaweed, beckoning him to join them. Of course, no one else can see them. This sets up a conclusion which is classic Rod Serling. Yes, it isn't all that surprising, considering the circumstances, but it is a very satisfying episode. The acting is quite good and the suspense builds well. A full hour may have been a bit long, but it didn't bother me as much as others.
