Group of knights templar get involved in the schemes and politics of the French court, while also on the hunt for the holy grail. Kind of a mix between arthurian legend and the 3 musketeers, nothing particularly original so far, I've seen up to ep 8 season 1, but it's been entertaining and I will keep on watching, however for a show made by the history channel I wish the makers put much more effort in to make it historically accurate, as its portrayal is very factually inaccurate.
