Merlin knows he must act fast before Morgana’s twisted control over Gwen gets further out of hand.
But only the most powerful magic can save the Queen and this will not be easy, even for Merlin. As the High Priestess tightens her grip on Camelot, one thing is clear - she will not give up her puppet without a fight.
Colin Morgan is Merlin, Bradley James is Arthur, Angel Coulby is Gwen, Katie McGrath is Morgana, Richard Wilson is Gaius and John Hurt is the voice of the Great Dragon. Tom Hopper, Rupert Young, and Eoin Macken return as The Knights of the Round Table.
