Nakamura Genji, noted commercial, feature and adult film maker presents his first "Pink Film", a radical look at gay sexuality in Japan. Shinohara, a young bodybuilder, joins a para military sect in northern Japan. His instructor, takizawa, takes a liking to the new recruit. 　　After an early "special" training session the two develop a lasting and loving relationship. Beautiful Mystery was the first gay "adult" film to come out of Japan. Although tame by U.S. standards, it is ground breaking nonetheless.
