"Eternal Law" is a fantasy drama set in York following the adventures of Zak (Samuel West) and Tom (Ukweli Roach), angels sent to Earth to work as lawyers on a mission to influence humans to do right by one another. Things don't always go according to plan, though, especially when they encounter old adversary and dark angel Richard (Tobias Menzies). In the first edition, Zak and Tom are plunged into a court case involving an estranged family and a newlywed. Created by Ashley Pharoah and Matthew Graham ("Life on Mars", "Ashes to Ashes"), the six-part series premiered on ITV in January 2012.
