The great Sofie Grabol is one of an ensembl cast in 'Prisoner', a Danish drama that explores the nightmare of the prison system, mostly from the perspective of the guards. Grabol is good as expected, but the whole cast play their roles nicely, although it was probably guilding the lilly a bit to have all three of the major characters compromised (albeit in different ways) by their relationships to prisoners. In spite of this, the individual elements of the story have a grimly plausible feel, and reminds one of how unwilling we are as a society to take the custody and rehabilition of criminals with the seriousness it deserves.
