A rogue grizzly bear is an 800-pound killing machine with a sweet tooth. When Tyler arrives in the Alaskan wilderness from San Francisco to spend the summer with his uncle Jake, he expects to fish and have camp fires. What Tyler doesn't expect is to be trapped in a small cabin with Jake too ill to help fight off a rogue grizzly who's gradually breaking in. Nothing in Tyler's easy city life has prepared him for anything like this.
