Plot: While visiting his mother on a construction site, a young boy, Quinn, finds a new species down in the tunnels…and barely survives to tell the tale. 20 years later, Quinn (Bale) leads a band of surviving humans, guarding against the next dragon attack. Quinn meets Van Zan (McConaughey), whose claims of killing a dragon help convince Quinn to travel to London to kill the only male dragon, in the hopes the species will die out without him, and give back the earth to humanity…what remains of it.
