Scream (1981)

A group on a rafting trip decide to spend the night in a ghost town.  When one of them is killed, they question whether the killer is a stranger or one of their group. Although the victim died while wandering off on his own, two others wander off alone during the night and meet their demise.

The next day they discover their rafts are gone. The nearest town is thirty miles away and no one will send a search party until they don't show up at their scheduled destination that night.  Despite the presence of a killer in town, the group decide to wait for help rather than leave.

Later in the day, two lost dirt bikers arrive and the group convinces one to let them borrow his bike to try to get help.  That night an old man on a horse, along with a dog, come into town with the body of one of the dirt bikers.  The old man tells them a confusing story about a sea caption and then leaves.

If you're looking for thrills or a revelation of who or what is doing the killings, or even a glimpse of the killer, you'll be sadly mistaken.  There is not a lot of dialogue and the music is right out of an early 80s tv show, think Hardcastle and McCormick or Magnum PI.  It's pretty slow moving and there isn't really a pay off since the killer's identity is left open ended.
