"Beneath Modern London Lives a Tribe of Once Humans. Neither Men Nor Women… They Are the Raw Meat Of The Human Race!"
There's something pretty grisly going on under London in the Tube tunnels between Holborn and Russell Square.

Helping them are a young couple who get nearer to the horrors underground than they would wish.
