Satan’s Triangle - 1975 - 6/10

Good title for erotic witchcraft exploitation, except this a Bermuda Triangle yarn.
Coast Guard helicopter responds to S-O-S distress from schooner out in the Sargasso.
Soon as the copilot drops onto deck, a freak storm appears and the chopper flies off.
Passengers and crew are dead, save for a companion B-girl (Kim Novak).
While she and copilot drink and drink, she relates how everyone aboard was slaughtered.
And reminds the copilot, “We’re going to die, too.”
May prove scary for the timid or easily frightened, otherwise fair at best.
