Dectective Larry Larwin calls Peter in the middle of the night about the murder of Mike Montog, a US police detective working on a counterfeiting and murder operation, and his entire family in their car by a bomb. At Montog's funeral, Peter learns that the murderer, Rik Allen, had evaded police survillance earlier that morning and a person matching his description was in seen around the Montog neighbourhood around the time of the explosion. More importantly, Allen has escaped to Brazil, a country that the US does not have an extradition treaty with. Peter now wants to dash out to Brazil on a personal vendetta to catch Allan and bring him back to Chicago for trial, but Alexander wants him to take the team to go to Brazil and dig out some concrete evidence that could be presented to the UN Commission on Extradition.
