A pair of dentists deal their own unique blow against the Third Reich in this low-key British comedy, which is actually based on a true story. In 1942, war rages all through Europe as Nazi Germany has taken France, attacked London, and defeated British forces at Dunkirk. In the midst of this chaos, Sgt. Peter King (Kenneth Cranham) and Pvt. Leslie Cuthbertson (Leo Bill) are serving in the village of Aldershot as part of the Royal Army Dental Corps, whose motto is "An Army Who Can't Bite, Can't Fight!" Eager to do more than fill cavities or pull wisdom teeth as the fate of Great Britain hangs in the balance, Sgt. King hatches a mad scheme to leave his post, make his way across the English Channel, and launch his own miniature invasion of France. Logically assuming that some assistance would be a good idea, he persuades Pvt. Cuthbertson to join him, and armed with ten grenades, a pair of pistols, and 20 bullets, they set out to take on the Vichy troops all by themselves. Derek Jacobi and Rosanna Lavelle highlight the supporting cast.
