In this first episode of a two-parter, Merlin and Arthur are sent on a dangerous mission to capture the Cup of Life, a powerful magical artifact that carries the gift of immortality. Before they can retrieve the Cup, they are captured by the unscrupulous slave trader, Jarl. Gwaine comes to the rescue and they escape, but with Jarl's help the cup falls into Morgause's hands. With an immortal army at their disposal, will Morgause and Morgana topple Uther once and for all?

Arthur and his loyal knights, including Lancelot, are forced to protect the kingdom when Morgana summons the mighty Callieach.

Merlin and Arthur find themselves vastly outnumbered in a tavern brawl, but an enigmatic man helps them to victory. The stranger risks his life to protect the Prince and is seriously wounded in the process. Arthur takes him back to Camelot where he quickly gets to work, drinking, charming the ladies, and causing trouble for Merlin. But when, what appears to be, two unscrupulous Knights try to kill the Prince, can Merlin and the inscrutable stranger stop them before it is too late?

With Merlin on the brink of death, who will stop Arthur from making the ultimate sacrifice to save his precious Camelot?

Arthur embarks on a solitary quest to retrieve the Golden Trident from the Fisher King and prove himself worthy of the Camelot throne. With the Prince beyond the protection of the citadel, Morgana sees an opportunity to use her dark magic and gives him a precious bracelet containing a Phoenix Eye. She insists he wears it at all times for protection, but it saps him of his life force and he is left defenceless in the Fisher King's perilous realm. With the help of Gwaine, can Merlin reach him in time and fulfil his own quest to protect the future king of Camelot?
