*Hoping to avoid an international incident, O'Neill and Teal'c lead a small combat team to face the deadly bugs aboard the submarine and to eliminate the threat to Earth. Their conventional weapons have a limited effect against the enemy, especially against the original Replicator, which has mutated into an enormous and nearly indestructible "mother bug". Destruction of the submarine is the only solution, and O'Neill and Teal'c find themselves trapped aboard the sub as they plant the explosives and desperately try to find a means of escape before the sub is destroyed.
