Here's one I did I thought you might enjoy.
On their vacation to a tropical island, the three young women were invited to a party at the home of a wealthy, handsome young man. Never did they image that they'd get lost on the way there and find themselves struggling for their lives in quicksand.
The soft ooze kept an iron grip on them as it slowly, inexorably pulled them down. Their vacation has become a nightmare.
