Series Three sees MERLIN return with the familiar blend of magic, monsters and mayhem. But when secrets are exposed and old friends choose new sides, it is clear that the kingdom will never be the same again.
Morgana is finally found after months of absence, and none in Camelot rejoice more than the King himself. But Merlin remains suspicious of his old friend and with good reason, for, despite what she may have others believe, Morgana wants only one thing to take over Camelot and shes prepared to do whatever it takes to achieve it.
Life changing decisions must be made as the boundaries of love, duty and friendship are pushed to their utmost limit, and the mettle of each character is tested in unimaginable ways. But in an uncertain future, only the strongest will survive.
