Need help identifying this 70's TV film

I remember as a child watching a movie on TV during the 70s that had a
scene like this:

A few people are trapped inside a Volkswagon van on a beach. It is
night, and they can only see outside as far as their headlights. The
sound of a stampede, & animals can be heard. A loudspeaker is telling
them not to leave the van, and they'll be safe from the animals.
Someone inside the van is screaming that there are no animals outside,
the loudspeaker is lying.

Does anyone know what movie this was from?

There was lots more that I don't remember. This was just one scene.
I believe it was a something-we-cant-explain-is-out-there Island-of-Dr-
Moreau/Lost type of movie.
