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.

After a group of biologists discovers a huge network of unexplored caves in Romania and, believing it to be an undisturbed eco-system that has produced a new species, they hire the best American team of underwater cave explorers in the world. While exploring deeper into the underwater caves, a rockslide blocks their exit, and they soon discover a larger carnivorous creature has added them to its food chain.
