An oil pipeline leak in the Gulf of Mexico looks like sabotage, and APO is assigned to find the source using any means necessary. Sydney and Dixon visit the drilling platform and discover a likely suspect, but before they can corner him, he flees...in the APO helicopter.
It seems the attack was a practice run for something bigger, and Sydney and Dixon must determine the real target before time runs out. There are other matters on the agents' minds too -- Dixon is concerned about his son, Steven, and Sydney is led to wonder, not for the first time, what it would be like to have a "normal" family. But there's no time for wistful thinking when the saboteurs' plot becomes clear...and threatens to throw the country into total chaos.
