维京岛国的少年小嗝嗝（杰伊•巴鲁切尔 Jay Baruchel 配音）是部落统领伟大的斯托里克（杰拉德·巴特勒 Gerard Butler 配音）的儿子，他非常想像自己的父亲一样亲手屠龙——这些飞龙是岛上维京人放牧羊群的主要天敌——但他每次出现在部落屠龙的战斗中都只给大家徒增烦恼。在一次对抗飞龙的战斗中，希卡普偷偷用射龙器击伤了一只最神秘的“夜之怒龙”，并背着族人放生、豢养，甚至驯服了这只龙，还给它起名“无牙”。希卡普的神秘行径引起了一同训练屠龙技巧的女孩阿斯特丽德（亚美莉卡·费雷拉 America Ferrera 配音）的怀疑。阿斯特丽德发现了希卡普的秘密，却同时被身骑“无牙”御风而飞的美妙体验所震撼。格雷决定在屠龙成人礼上向远征归来的斯托里克和族人讲明真相，说服大家放弃屠龙，却偏偏弄巧成拙，害得“无牙”被俘，一场更大的灾难就在眼前……...
The film tells the story of single mother “Kara” (Elizabeth Roberts) who moves from New York to the quiet countryside with her two children for a job opportunity she can’t afford to turn down. The family moves into their humble new guesthouse. Kara begins her work as a private nurse to “Walter,” (Bruce Davison) a man stricken with multiple sclerosis and an appraiser of rare antiquities with a secretive past.
Her teenage son, Jesse, (Arman Darbo) is unhappy about this most of all. Losing his friends and moving to the middle of nowhere hasn’t made his job of looking after his little sister, “Cambria,” (Chloe Perrin) any easier.
Doom precedes them. “Akiba,” (Treva Etienne) a shady international associate of Walter’s, brings with him a mysterious relic of ancient origin. “Kara” encounters run in with a local sheriff played by genre veteran actor Denise Crosby.
All too quickly they discover the relic contains more than just legends. Inside, waits a terrifying creature born of ancient darkness and pure instinct…a pre-historic cave Spider unlike the modern world has ever seen.</p>...
