After a storm on the North Sea in 1991, the peace of a routine spring morning is shattered when a secret German World War II chemical weapon washes up on the shore of a small Scottish fishing village, killing scores of inhabitants in a gruesome, painful manner.
Retired U.S. Navy Bomb Disposal technician Mack Turner and his newly organized GREEN Team are dispatched to discover the cause of this mass murder and remove the threat before it can create additional destruction. While in Scotland, the team discovers the depth of the German plot and the imminent threat to New York City. Before they can mitigate the situation in Scotland and return to the United States to stop another disaster, a dangerous man from Mack's past hijacks the chemical weapon from its resting place in the United States to use in his own twisted plot of revenge.
In a heart-pounding race against time, the GREEN Team must utilize all their resources to outthink the chemical terrorist and deal with his dangerous physical and psychological impediments. Can they stop the madman in time, or do the citizens of New York City face certain death?
