歡迎來到比弗米爾斯，這個孤立的阿拉斯加小鎮迎來了它沒有夜晚的盛夏季節——極晝。短暫的樂趣很快結束，當地開始發生人員失蹤，還有壹些人的遺骸被發現。蜿龍（Wyvern），壹種長有翅膀的史前爬行動物，它從冰冷的海底逃脫，肆虐大地。小鎮最後的機會就是，從野獸的窩中竊取壹枚蛋。
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.
