After the immortal God Zeus, king of the gods, has a particularly boring period in his existence, he decides he wants to have some fun with a few humans. He invites four people to meet him at his temple where he explains he wishes to give the gift of immortality to one of them but they have to prove there worth.
To do this, he leads them to a maze at the back of his temple where he bluntly states that the first person to get out the other end, if anyone at all does, will be granted Immortality and be recognised as a friend of Zeus.
