I watched it a long time ago and I have no idea who is in it so I will describe it the best I can. A man ties heavy, sinkable things to people and he throws them into I think it's a lake and made like his own underwater graveyard. And one girl gets away and helps them catch him.

The movie you are looking for is Cabin by the Lake, it starred Judd Nelson.
