Dir: Pete Walker
Starring: Patrick Barr and Sheila Keith
A disgraced matron and a former judge mete out punishment as they preside over a secret correctional institute for girls
This seventies horror exploitation movie is considered to be better than most of the time, with some critics claiming it to be a ‘disturbingly effective thriller’. It features a passing shot of an express hauled by a ‘Peak’ diesel and some good shots of Lydney station in Gloucestershire.
