For every action, there is a consequence.

Germany's elite Department 89 has crossed paths with the Central Intelligence Agency on more than one occasion. But after their last encounter, Langley decides enough is enough.

Sending a covert black-ops hit team to Berlin, the CIA Director orders the deaths of the Department 89 chiefs and the obliteration of the entire department. A deadly message must be sent to German Chancellor Claudia Meyer, and Agent Tom Finn is the messenger.

But Finn and his team have never met anyone like Department 89 before. By the end, there can only be one victor - and Finn is on Decker's home turf.
