This is a clip from the recently filmed Murder on the Orient Express by Agatha Christie (SPOILERS btw).
Near the end of the film Christie's famous detective, Hercule Poirot (pwar-OH), discovers that the murder was committed by all twelve suspects, who collectively sought revenge against the victim, a child murderer whose actions resulted in the deaths of five innocent people. He was arrested and tried, but because of some legal loophole he walks.
So now there are twelve people all closely related to the victims in one way or another. They are bitter that the law did not mete out justice, so they resolve to take the law into their own hands and carry out a vigilante execution while on board the Orient Express.
Poirot represents Ti. I believe him to be LSI-Ti 1w9 sp/so. He strongly believes in the rule of law and is outraged at the twelve passengers taking it into their own hands. His position is that if we ignore the law then civilization will break down into anarchy. The passengers represent Fi, and see Poirot's viewpoint as inhumane and unjust, as it resulted in the freeing of a psychopathic murderer.
Here's the showdown. And by the way, he very reluctantly capitulates and lets them go free at the end. The last shot is him walking away from the suspects while tearing up, devastated at violating his principles. He takes a role/polr hit but I think he did the right thing, seeing that though his moral convictions are sound, there are indeed gray areas in life.
