秘湯の街　夜のひとで (1970)

This humorous film provides a fascinating insight into Japan’s pornographic underworld, following a band of itinerant smut-peddlers, consisting of Hisao, his wife and main model Saku, and their partner in crime Tori, as they arrive, penniless, at a hot spring resort and attempt to make their money selling nude photos, staging live sex shows and screening homemade blue movies.
