On a mission SG-1 finds an ancient, apparently lifeless metallic sphere-shaped object and brings it home to study the minute, elaborate writing on it, hoping they can then open it. Jack was eager to get away from the tedious examination, which seemed to be going nowhere, on yet another planetary mission, when the sphere suddenly 'warms up' and surprises everyone by sprouting long spikes in various directions, one of which happens to go straight trough Jack's body which soon infects.

While visiting a desolated planet similar to the moon, Jack, Daniel, Samantha and Teal'c find a spherical object and Jack decides to bring it with them to study.

General Hammond seals the base and cut-down to self-destruction. However Samantha discovers that the orb feeds of energy and will grow with the blast. But the self-destruction process cannot be stopped since the computers are infected with the alien virus.
