So he travels to Zurich, secures the funds, and tells his wife to make an offer on her dream country mansion. What Tom doesn't know yet is that his father was being used as a 'ghost' to clean up dirty money by a New York laundry operation: really the money belongs to Carlos Morales, Medellin's biggest cocaine baron.

Tom's actions in Europe spark a murderous turf war in the Americas between the cartels of Medellin and Cali, involving a cast of bent lawyers, cops, undercover DEA - and transatlantic assassins who'll stop at nothing or no one to make Tom pay his debt...
