In ancient Japan a crime take place as told from three different travelers who have experienced the crime: a man being killed and his wife being raped. Which if any of the stories is true? A Akira Kurosawa film about morals, truth, and communication.
Synopsis (spoiler free): Three men gather together in the ruins of an old Japanese gate house to escape a rainstorm.
Indeed it's story was so revolutionary and influential that the film has become shorthand for this type of tale (the Rashomon effect), and has been used numerous times both in film and TV The Usual Suspects, Hero and episodes of The Simpsons, The X-Files, Leverage, Star Trek: The Next Generation and CSI amongst many others I'm sure all used its structure as inspiration.
