Saw this on Prime so its old, but now cannot find it. A couple on a date goes on a sightseeing tour and gets off to explore a park/forest. The bus leaves without them and they get lost in this forest so no one knows they are in the forest. They become disoriented and travel far away from the bus stop and civilization. They come upon an old campsite with tent and find the body of the former camper. He has left a diary that indicates he got into this forest, but there is no way out. He has left behind some supplies that includes matches. The couple starts a forest fire and is rescued when helicopters come to investigate the fire.
