Fear in the Forest.

Jasmine has mixed feelings about her visit in the United States. Her friend Julie has taken her on her first camping trip, and so far it has been more than either of them had bargained for. Just two days ago, they had been captured, tied and tickled by a deranged woodsman (See The Happy Woodcutter). They managed to escape only to find their car wouldn't start. Now they have to make their way back to the village on foot. This means two more days of camping out. To make matters worse, there's another lunatic prowling the woods. When he spies the beautiful oriental Jasmine, he has a flashback to his tour duty in Vietnam. Unable to distinguish reality from delusion, sees Jasmine as a Viet Cong. He captures her, ties her up and subjects her to a cruel interrogation. Julie is soon captured and treated in a similar manner. What started out as a fun camping trip has turned out to be an ordeal of bondage and terror.
