After the death of her youngest son, single mother Kara and her two children move from New York City to the other side of the country. She finds a job as a nurse with Walter, a wealthy, lonely, elderly widower who has provided her family with a whole house. Walter collects archaeological rarities, and just the other day he is brought an artifact stolen from a savage tribe, intended for the worship of a local tough goddess. Soon the ancient vessel shatters, a giant spider crawls out of it, and begins collecting bloody victims.
