Etsuraku / Pleasures of the Flesh - by Nagisa Oshima (1965)

A corrupt businessman blackmails the lovelorn reprobate Atsushi into watching over his suitcase full of embezzled cash while he serves a jail sentence. Rather than wait for the man to retrieve his money, however, Atsushi decides to spend it all in one libidinous rush—fully expecting to be tracked down and killed. Oshima’s dip into the waters of the popular soft-core “pink film” genre is a compelling journey into excess.
