Episode 54 - Inferno

Man has always strived to break new ground in the name of

is broken and a unimaginable fury was unleashed? This week Paddy
and Tricia watch as The Doctor goes head to head with the
egotistical director of a project to break through the Earth's
mantle. Can The Doctor protect the Earth from being engulfed in a
catastrophic Inferno?
