Channel 4's 'dark' 8-part crime drama Hellground is the ultimate 30-minute episode binge

The series, which Channel 4 describes as a "dark" thriller, is set in the small, tight-knit village of Black Forest, where a string of mysterious deaths catches the attention of local police officer Tanja. 

The full synopsis reads: "Welcome to Hellground, where country doctors aren't heroes, they're suspects. In this eerie Black Forest village, a routine house call can have deadly consequences, and a police investigation threatens to unravel the entire community. 

"When a string of mysterious deaths strikes the peaceful town, local officer Tanja is the only one who senses something sinister beneath the surface. Battling silence and suspicion, she begins to dig and all clues lead to the charming young village doctor, Fabian, whose healing hands may be hiding deadly secrets."

The series has been praised as a "great" and "entertaining" watch by viewers online. 

One person penned: "A highly successful German thriller series with fantastic acting, great dialogue, plot, and a great score. Definitely recommended if you like a bit of off-the-wall action," while another added: "It starts off a bit slow, but develops into a blast. I found it very entertaining."

A third fan remarked, "I'm watching it for the second time now. Really, the best German series."

The series features a cast of German talent, including Lou Strenger (Tanja Hartholz) and August Wittgenstein (Dr Fabian Lambert).

They're joined by Nicki von Tempelhoff as Josef Hartholz, Andreas Anke as Werner Freischütz, Ulrike Tscharre as Moni Freischütz, Jakob Gessner as Max Freischütz and Heiner Lauterbach as Dr Hajo Armbruster.
