Based on the Belgian series of the same name. Professor Jasper Tempest precisely calibrates and structures every aspect of his life. Impeccably dressed and meticulously punctual, he lectures daily at the Cambridge Institute of Criminology, teaching students imaginatively, if pedantically, about the science of crime. Each evening, he returns home to his apartment, which is as sterile and systematically ordered as a science lab. Thanks to this strictly regimented approach, his OCD and germophobia are under control. But Professor T's buttoned-down world is slowly undone when he is persuaded by one of his former students to assist in investigating a serial rapist. The Professor's encyclopedic knowledge of criminal psychology and his brilliant mind prove invaluable to the team, but the cracks in his carefully constructed emotionless exterior begin to show. -- Adapted from container and PBS website.
