Those inside the Paris Temple of the Knights Templar find themselves sorely under siege in the new episode "IV." While the cunning De Nogaret (Julian Ovenden) sows seeds of doubt and suspicion in the mind of King Philip (Ed Stoppard), Queen Joan (Olivia Ross) wrestles with the question of what would be in the best interest of the people of Navarre. Tom Cullen, Padraig Delaney, Simon Merrells and Jim Carter also star.
