Long Weekend (1978)

In Australia, Peter and his wife Marcia travel with their dog Cricket in their Jeep to camp along the weekend in a remote beach. They spend most of the time arguing with each other since Marcia wants to go to a hotel instead of camping. Peter holds a grudge against Marcia since she has betrayed him with their friend Mark and Marcia had an abortion later. But sounds of nature may be scary for urban people.
