Mosk, a tough and brutal inmate of a high-security prison, is given the opportunity to take part in a programme for the training of guide dogs, simultaneously a programme for reintegration. Against his will he soon develops a close emotional relationship to the little puppy put in his care, and this changes his entire frame of mind. Even the relationship to the previously hated female prison director changes. But when Mosk is required to give back the dog, the pain of separation drives him to a deed of desperation. Director Jan Hinrik Drevs (“Mr. Pilipenko and His Submarine”) came across the subject while doing research for a documentary film about reintegration programmes in the USA. The unusual friendship between man and dog fascinated him to such a high degree that he developed the motif into a feature film format.
