Its about a girl in yorkshire, UK in the 80's that remembers she used to be a boy in the past.
When she was a boy his foot got caught on a train pedestrian level crossing grid, and couldnt free his foot in time and was killed by a train. She remembered the surname benson I think it was and the location.
They find the name of the boy in the records. They find the old house where the boy lived ( its been abandoned and falling down). The end of the interview she talks about it at the level crossing where it happened, she clearly is distressed talking about it with a weary look and sigh. I think that covers it
