“Blunt Talk” follows Walter Blunt, a British import intent on conquering American nightly cable news and the fallout from his well-intentioned, but mostly misguided decision-making, both on and off the air. Through his show, Blunt’s mission is to impart his wisdom and guidance on how Americans should live, think and behave. Besieged by a dysfunctional news staff, his only support is the alcoholic manservant he transplanted from the U.K.
