Arctic bush pilot Harry McNills is minding his own business and dreaming of retiring to the Caribbean--when two scientists from Cryolabs Corporation charter his plane for a scientific expedition. The beautiful young biologist Amy Tyler and her boss, the avaricious Hayden Lockwood, want to explore for freeze-tolerant organisms. Harry gets more than he bargained for when he falls for Amy and discovers an ancient terror entombed in an iceberg. A Navy team is assembled to exhume the remarkable find. But before the job is completed, something goes horribly wrong...and Harry and Amy find themselves trapped in a desperate struggle for survival.
