It was a kind of portal - a portal into the myths of the ancient world...

Everyone knows the Doctor loves museums (it's his way of keeping score).

But when Jo Grant and the Doctor visit the British Museum in London, they might have got more than they bargained for.

A mysterious object is revealed, which grants those who touch it strange visions of Greek Myths. Gods, warriors and monsters are contained within this object - the MythoScope.

But there is something sinister at play. A powerful influence seems to be controlling the mythoscope...mastering it.

Jo and the Doctor must bargain with Zeus, battle the undead and journey to the ends of the Earth, where only an object of wondrous power can save the MythoScope from total destruction.
