Exploring a lifeless world – one which Teal’c is certain once supported abundant life – SG-1 encounters an unusual artifact which seems to be emitting a power signature, despite being at least a thousand years old. Carter and Daniel both set about trying to explore the object’s mysterious nature, with a definite deadline: the NID organization wants to study its power source. When the artifact finally activates, it seems determined not to let anyone interfere with it. O’Neill and Teal’c rush it to the gate room to dispose of it, but the object fires metal spikes into the walls and floors, impaling O’Neill through the shoulder and the concrete wall behind him. General Hammond orders a lockdown of the base, and Dr. Fraiser discovers an alien organism is also being released by the device, infecting the entire base. Even when Hammond sets the base’s auto-destruct, he may be unwittingly providing the organism with the means to overrun the entire Earth.
