Edinburgh, 1820s.
But can be balance its pow.
Only a relic of the past - a dark, carved staff - seems to give Martin respite.
Ghosts of the long-dead haunt the houses, and nightmares soon fill Martin\'s head.

When newly qualified Doctor Martin Elliot arrives, he discovers that the duality goes deeper.
On the other is the New Town - elegant, refined and prosperous.
On one side is the Old Town; ancient, crumbling and full of poverty.
