KMC Forums - 80's slasher film title needed...help

o.k.
i could use some help looking for the title of an obscure 80's horror/slasher film.
the scene that i remember is that this bunch of 20 somethings are on a small plane and it goes down,they are stranded on an island of some sort.now i still may not have this correct but i am positive that the group of kids are around a campfire partying,drinking listning to some music and they engage in a truth or dare/spin the bottle scene that gets a little out of control and tempers flare.
i know it is not "american gothic"as in that movie a plane goes down with 20 year olds but thats not it.i have that one and the other is different as i saw it once on h.b.o. along long time ago.
if anyone out there knows the title of the movie with the scene i just described i would appreciate it.
i usually dont forget these things but this is like almost 30 years ago .

anyone????
