Dave Arnold and his crew at the Isle of Wight Military History Museum are set for a real challenge. They've rescued a rare 1945 COMET Tank from an Army firing range. It's been shot to hell and they only have four months to get it ready and running for the crowds at Tank Fest 2006. We'll see tons of action in the shop as they tear it apart; overhaul the engine; strip, sandblast, paint and put it back together again. Along the way, we'll find clues in the form of serial numbers and markings that retrace the war-time mission of tank and crew behind enemy lines; from the crossing of the Rhine to confrontation with the deadly Panzerfaust, and the final race for Berlin.
