The show, which has the absolutely amazing trio of Ben Whishaw, Romola Garai and Dominic West in the lead roles, focuses on the people working on a current affairs television programme in the 1950s.
As if that wasn't enough, there's a creepy murder mystery to unravel and, of course, some gorgeous period detail to drool over.
