i remember seeing it a few times in the 80s but it may be 70s era.
Sadly, all I remember is a body wrapped in a white shroud. A man is going to bury it on a sandy beach and as he gets it ready or once it’s in the hole blood starts soaking through the shroud. That image is burned into my brain but I’ve never been able to recall more.
Help?
