Merlin: The Last Dragonlord

SYNOPSIS

The Great Dragon is finally free, and attacks Camelot. With the castle crumbling, the knights cannot hold out much longer - only a Dragonlord can kill such a beast and Uther wiped them all out years ago, or so it is believed. Gaius reveals one such man may still be alive and in hiding, so Arthur and Merlin set out in search of him, before the kingdom is destroyed. But even if they find him, can they persuade him to help his old enemy Uther? Colin Morgan, Bradley James, Richard Wilson and Anthony Head star, with a guest appearance by John Lynch. Last in the series.
