This is a fast paced plot which starts out in North Korea where Lea, one of the NSA agents gets beat up and returns to USA. Meanwhile Tommy and Dean, NSA agents, follow leads of a case un Great Britain and then off to France. The basic plot is an Arab, Musa, who is going to blow up the Eifel Tower and the English Channel train tunnel in vengance for the death of his father. Tommy aborts the Tower bomb through an audacious climbing and shooting. Lea and Dean take care of the Tunnel bomb. As usual there is lots of tech talk to the "Art Room" which is in the NSA headquarters.
