The actual story, Rashomon
(the story of the murder
from different perspectives
is titled In A Grove
), is about a famous gate into Kyoto
which, as the city fell into despair (the story attributes this to a series of "calamities
"), the gate
became a place infamous as a hideout for thieves
and other criminals
as well as a place to dispose of unwanted bodies
The story concerns itself with a man who has lost his job and, penniless, homeless and hungry, takes shelter under the gate and finds a woman doing some disrespectful things to some of these bodies (get yer minds out of the gutter, it takes place in Ancient Japan. Necrophilia may have existed (if it exists at all), but it wasn't exactly a topic to be discussed in that setting, even when Ryunosuke Akutagawa wrote the story in the early 20th century).
The rest I leave up to you going and finding a copy of it somewhere and reading it (it's a short story (all 6 stories bundled in the version I've got come to about 100 pages) and I sure do hope I didn't say too much). All the stories in the collection are quite good and thought provoking.
