imagine the engineer drives that train night after night picking up containers and moving them to another railyard. the engineer hears voices coming from some of the railcars. he tells his superiors. his superiors tell him to fuck off (because they are all getting a piece of the action).

finally he sees his chance to create a big scene so maybe people who come to investigate can see or hear the people in the containers also.

sadly he doesn't know, the investigators are getting a piece of the action also.

he is labeled terrorist and no one listens to his story.
