欢迎来到比弗米尔斯，这个孤立的阿拉斯加小镇迎来了它没有夜晚的盛夏季节——极昼。短暂的乐趣很快结束，当地开始发生人员失踪，还有一些人的遗骸被发现。蜿龙（Wyvern），一种长有翅膀的史前爬行动物，它从冰冷的海底逃脱，肆虐大地。小镇最后的机会就是，从野兽的窝中窃取一枚蛋。
Welcome to Beaver Mills, an isolated Alaskan town celebrating its midsummer season of no night. Soon enough, the fun is over when locals start to go missing and human remains are discovered. The Wyvern - a prehistoric winged reptile - has escaped from its icy ocean grave and is now gorging itself on every living thing on land. The towns last chance to defeat the creature is to steal an egg from the beasts nest. But theres no force more ferocious than a starving mother protecting her young.
