More4 continues its offering of top quality foreign language drama. This Belgian crime series is about a forensic psychologist who is also a professor and advisor to the police. Prof. Jasper Teerlinck is a gifted eccentric who suffers from extreme OCD and may be on the autistic spectrum (possibly some Sherlock Holmes inspiration here?). In this opening episode, a balaclava-clad rapist is terrorising and attacking young women at a university campus. Inspector Annelies Donckers seeks advice from Teerlinck, who is her former college professor, on the case, which seems to have more than a few similarities with a cold case from ten years prior.
