In post-apocalyptic England, an American volunteer and a British survivor team up to fight off a brood of fire-breathing dragons seeking to return to global dominance after centuries of rest underground. The Brit -- leading a clan of survivors to hunt down the King of the Dragons -- has much at stake: His mother was killed by a dragon, but his love is still alive.

For years, old wood carver Mr. Meacham has delighted local children with his tales of the fierce dragon that resides deep in the woods of the Pacific Northwest. To his daughter, Grace, who works as a forest ranger, these stories are little more than tall tales... until she meets Pete, a mysterious 10-year-old with no family and no home who claims to live in the woods with a giant, green dragon named Elliott. And from Pete's descriptions, Elliott seems remarkably similar to the dragon from Mr. Meacham's stories. With the help of Natalie, an 11-year-old girl whose father Jack owns the local lumber mill, Grace sets out to determine where Pete came from, where he belongs, and the truth about this dragon.
