Above the Law

1988 ★ 6.2
as FBI Agent Halloran

Sergeant Nico Toscani, who traces his roots to Palermo, Sicily, is a detective in the Chicago Police Department's vice squad. At an early age he had become interested in martial arts, and moved to Japan to study them. In 1969, Toscani was recruited to join the CIA by Nelson Fox and was involved in covert operations on the Vietnamese-Cambodian border during the Vietnam War. There, he became disgusted with DCI Kurt Zagon, who tortured prisoners. A stand-off occurred when Toscani tried to stop a torture session, and he left the CIA. Toscani returned to Chicago, joined the police department, and got married. Toscani and his new partner Detective Delores "Jacks" Jackson are investigating a drug ring, and after busting two of the dealers, including Salvadorian drug lord Tony Salvano, Toscani finds C-4 explosive. Shortly afterward, the men that Toscani and Jackson arrested are released at the request of federal officials, and Toscani is ordered to stand down. Later, the priest of Toscani's parish is killed in an explosion during Mass. Fox calls Toscani and tells him to move his family to a safer location, saying that he is in danger. Under pressure from the feds, Toscani is asked to turn in his badge. He eventually discovers that the dealers he busted are linked to Zagon, who is still with the CIA, and who is being accused of human rights violations by a Central American priest who was being sheltered by Toscani's priest. While Zagon is torturing the priest, Toscani bursts in and a gun battle ensues. Detectives Lukich and Jackson are wounded during the shootout, and Toscani has to flee. Senator Ernest Harrison is investigating Zagon's group to reveal their covert operations and drug dealing. When Toscani finds out that Zagon killed the priest and is planning to kill Harrison, he goes after Zagon. Toscani confronts Fox, but they are interrupted by Zagon's men. Fox is killed and Toscani is captured. He is held in the kitchen of a hotel during a Harrison campaign rally. Before Zagon can kill Harrison, Toscani breaks free and kills Zagon and all of his remaining men. After, Toscani meets Harrison, who has been informed of everything. Harrison promises justice and Toscani says he is now willing to testify about his experiences with Zagon and covert operations in the CIA.
