I'm trying to remember the name of a (somewhat horror) movie in which some people get somehow stranded in a boat , and as usuall, things go wrong.
The main plot is that some giant lampreys (snake-like sea creatures) attack the crew.
There is not much to say about the plot, other than the creatures are big ass lampreys, and the usual "everyone gets killed one at a time" of this kind of movies.
I estimate it is a 90's movie.
SPOILERS from here on
at the end, only a few members get it out of the ship, and manage to get to a nearby island, only to realize that they landed on a lamprey infested place. The movie ends with a birds view of such island, and we hear monstruous noises and trees moving around as if they are attacking each other...
