Discovering a new cave in Gower Ogof New Park

This is discovery story. You follow the exploration from the very beginning of the excavation on the surface right through to the final passages 400m deep under the fields in North Gower, a coastal peninsula in Wales , UK. Almost all the film uses video taken during the moments of the 1st people in the team , travelling into the unknown. The cave is extremely narrow in places. Only the very thin will get in and out again.
