A team of experts excavates a famous WW1 battlefield in search of a top secret tunnel and a giant 60-foot flame-thrower. Historian Peter Barton and archeologist Tony Pollard travel to northern France to find secret tunnels and a giant flamethrower lost for almost a century.
Built for use during the opening day of the Battle of the Somme, the bloodiest clash of WW1, this 60 foot weapon of terror fired a blast of flaming oil over 100 yards long.
Barton hopes to recover the machine and with the help of the British Royal Engineers, build a working replica at a specially built test site. For the first time in almost a century, this mechanical dragon will roar once more.
