"The Tunnel: Vengeance" is set amidst post-Brexit hysteria, an escalating refugee crisis, and the increasing threat of terror occasioned by disenfranchised, exiled souls on whom society has turned its back.

Karl and Elise take on a toxic and terrifying folie à deux whose mutual defining quality is an existential deathwish. When the question posed by the couple – what is a life worth? – is directed straight back at Karl, he is forced to confront an utterly impossible choice.
