In Sniper 3, Thomas Beckett (played by Tom Berenger) is approached by a former protégé and friend, Gunnery Sergeant Brandon Beckett (played by Chad Michael Collins), who has since become a top-notch sniper himself. Brandon requests Thomas' help in a mission to track down and eliminate a Serbian general who is responsible for war crimes.
Thomas initially declines, but changes his mind when he learns that the general may have had a hand in the death of his own son. Together, Thomas and Brandon embark on the mission, but soon find themselves in over their heads when they are ambushed and forced to fight for their survival.
As they make their way deeper into enemy territory, Thomas and Brandon encounter a group of female freedom fighters who are also hunting the Serbian general. Together, they must navigate treacherous terrain and outsmart the enemy in order to complete their mission.
Throughout the film, Thomas struggles with the guilt and trauma of his past missions, particularly those that involved killing friends and former allies. He also tries to reconnect with his estranged wife, who is unaware of his current mission and his involvement with Brandon.
In the climactic final showdown, Thomas and Brandon face off against the Serbian general and his army, with the help of the female freedom fighters. The action-packed sequence ends with a tense sniper battle and a surprising twist that leaves Thomas questioning his own sense of duty and justice.
