Based on stories by VL Whitechurch and M McD Bodkin.
Written and directed by John Taylor.
In the 1920s in a compartment of the Glasgow to London sleeping-car express, two men and a woman debate unsolved railway mysteries.
But the travellers become aware that another story is emerging - one in which they are all involved and which is hurtling towards an extraordinary conclusion.
