About The Tunnel

The Tunnel is a British–French crime drama television series adapted from the 2011 Danish–Swedish crime series The Bridge (Bron/Broen). The series began broadcasting on 16 October 2013 on Sky Atlantic in the UK, and on 11 November 2013 on Canal+ in France. The series stars Stephen Dillane and Clémence Poésy as British and French police detectives Karl Roebuck and Elise Wassermann. The plot follows the two detectives working together to find a serial killer who left the upper half of a French politician and the lower half of a British prostitute in the Channel Tunnel at the midpoint between France and the UK. The killer is nicknamed the "Truth Terrorist" and is on a moral crusade to highlight many social problems, terrorising both countries in the process. As the series progresses, the killer's true intention is revealed.
