The series stars Lowden as Gunther, a cop who receives a promotion to join the elite and intimidating Berlin Murder Squad. Gunther is tasked with the responsibility of looking into what appears to be a killer who targets those who are on the fringes of society. Berlin offers him much freedom to operate and, at the same time, has much turbulence, with the Nazi reign a nightmare about to happen. As the social and political world shift to a completely new norm, Bernie must fight for truth, no matter what the cost may be.
Meanwhile, Firth stars as a brilliant yet prickly detective named Paul Lohser, who is part of the Berlin Murder Squad and is an antithesis to Bernie. At the same time, Lohser serves as Bernie’s ally as he tries to catch the killer.
Firth’s upcoming projects include a role in Disclosure Day, the Steven Spielberg directorial, Prime Video’s Young Sherlock, and a role reprisal as Harry Hart in filmmaker Matthew Vaughn’s Kingsman: The Blue Bloods.
