With Camelot in Morgana's clutches and Merlin and Arthur on the run, the young King must regain his confidence before all is lost forever.

Morgana launches a ferocious attack that leaves Arthur in grave danger. It's up to Merlin to save the King.

Morgana finds a powerful ally to help her force Camelot to its knees. Meanwhile, Arthur is preoccupied by the arrival of a beautiful princess.

The team are faced with one of the most dangerous threats they have ever come across - a flesh-eating fungus that turns its victims into human shells intent only on spreading the fungus further. It takes over any person who comes into contact with it, and it proves resistant to everything the team can throw at it.

Featuring a historian who can't quite control his arms, a supervillain who gets a little bogged down in health and safety, and the world's least politically-correct pantomime. Plus, a look behind the scenes at the admirable work done in the pheasant hospital.
