Sniper 3

In Ho Chi Minh City, Beckett meets his contact, NSA-recruited Vietnamese police operative Quan (Byron Mann). Beckett is shaken due to the personal nature of his task and calls Sydney, forgetting the time difference. Beckett tells Sydney that he just wants her and Neil to know how much they mean to him, as he never truly had a family of his own. Later that night, Beckett goes to the Club Cong, to kill Finnegan (John Doman), while he is having a drink. However, he fails to complete the mission and is shot at by a counter-sniper. Beckett kills the sniper but is arrested by Vietnamese authorities. In custody, Beckett sees Finnegan in another cell, who claims that he abandoned his wife and child because he felt "alive" in the jungle, but claims that he was "sold out" by the very people he worked for. Finnegan blows up the police station to escape, which gives Beckett an opportunity to escape as well. Beckett contacts Quan who demands that he provide him with a weapon and a way home. Suspicious of the purpose to his mission, Beckett wants to find Finnegan and get to the bottom of things. He locates Finnegan in "the ditch", old Viet Cong tunnels under Tây Ninh after he and Quan defend themselves from an ambush.

During the infiltration of the tunnels, Quan accidentally loses his footing and slips in front of Finnegan who holds him at gunpoint, but reveals the truth to Beckett. After he was recruited and began working for the CIA, Finnegan was in the ditch with John Gaylor, Bill Avery and a civilian AP photographer named Stevie York, who filmed their activities. York watched as the three men, high on drugs, killed nine unarmed civilians (six men and three women) over the course of three days. The men made York destroy the film, but, paranoid from the drugs, killed him and made it look like the NVA did it. Now that Gaylor is a Senator from Texas and is running for president, he cannot have Paul get captured and expose his past, so he asked Avery to trick Beckett into eliminating Finnegan, and then have another sniper kill Beckett to keep any information from getting out. Quan is forced to fight and kill one of Finnegan's top henchmen in hand to hand combat. In order to save Quan, Beckett kills Finn by shooting one of Paul's child soldiers in the hand and triggers an involuntary jerks of his other finger., resulting in Paul being shot in the head instead of Quan. With nothing left to fight for, Finnegan's militia surrenders and leaves. Afterwards, Quan and Beckett say their goodbyes and Quan arranges a retrieval for Beckett just over the border in Cambodia. Beckett is shaken and disillusioned by the experience, and on the way home he learns from a radio broadcast that Gaylor resigned his seat in the senate and ended his political career before he could become president, and Avery was found dead in an apparent suicide.
