After a loaf of bread is accidentally contaminated with rat poison a desperate police search is made to find it
This taut little B thriller contains an excellent shot of ex-GWR 9400-series 0-6-0PT No.9422 running light engine and stopping next to a drunk who has fallen down a railway embankment. This was filmed adjacent to the footbridge to the east of Beaconsfield station, which is just visible in the far distance.
