An alien starship crashes in a swamp in a U.S. National Park. Some mosquitos begin to feed from the alien"s corpses, causing them to grow to the size of a vulture. These mutant insects became very agressive, killing every human being they find. Will the few survivors fight successfully against this nightmare...?  　　关于蚊子的设定有硬伤，首先，如果蚊子的体积增加到和人差不多大时，同比增大的翅膀就不能带动身体飞翔，即使能，也不会飞翔时发出嗡嗡声。 　　其次，孑孓至少也要差不多大小，那它们的食物来源也有问题。 　　 　　如果将蚊子的大小设定在成人拳头大或更大一些的话，以数量杀人的，一定会更好。
