Plot
After the events of Wolf Warrior, Leng Feng and members of his special-ops team bring his fallen comrade's remains back to his hometown. As the family prepare for the funeral, a real estate company is about to demolish their house. The boss of the real estate company sneers at Feng and his team for their patriotism, and he is kicked to the ground. The boss orders his henchmen to attack Feng and his team, who swiftly disable them. Police arrive shortly after and order Feng to stand down. The boss boasts that he will "make the family wish they were dead", enraging Feng, who kills him. Feng is sent to a military prison for two years and then discharged from the Chinese army.
After his release from prison, Feng leaves for Africa, planning to wander aimlessly around the continent. While serving as a mercenary providing security for a freighter delivering relief supplies to Africa, he foils an attempted hijacking by Somalian pirates, defeating them in hand-to-hand combat underwater. For three years, Feng has been carrying a bullet he found, which was a clue to the kidnapping of his fiancée, Lieutenant Colonel Long Xiaoyun, that happened while she was on a mission.
Feng and some locals are partying on a beach when they are attacked by rebel forces aiming to overthrow the African nation. Shortly after the rebels and their mercenaries overrun the government troops, the Chinese fleet arrives to evacuate Chinese nationals. While on board a Chinese military ship, a shop owner that Feng rescued informs him that the bullet he is carrying belongs to European mercenaries who are helping the rebels. Feng volunteers to rescue workers at a Chinese factory and also a VIP, Dr. Chen, who was held hostage in a nearby hospital. Chen is developing a vaccine for Lamanla, a deadly endemic disease. However, Feng will be on his own; no Chinese military personnel could accompany him because they are on foreign soil, and must wait for permission from Chinese military leadership and United Nation Security Council approval.
Feng travels to the hospital; during the hostage rescue, Chen is accidentally killed by the rebels and their mercenaries. Dying, Chen tells Feng to take his daughter, an African girl named Pasha. The mercenaries are led by Big Daddy, a ruthless American working for Dyon Corps. Feng and Pasha, together with Rachel Smith, a surviving doctor, escape, but Feng cuts his hand when he falls on some Lamanla-infected corpses.
Feng continues to the Chinese-owned Hanbound factory to save the workers, among whom is his godson's mother. Upon arrival, Feng is confronted by the suspicious factory security team led by the factory owner's son, Zhuo Yifan, a cocky fuerdai young man who is also an ardent Chinese army fan. Feng informs everyone that the Chinese fleet plans to send a helicopter to rescue them. The women and children will evacuate via helicopter and everyone else will travel by road to join the fleet.
Big Daddy's mercenaries attack the factory to capture Pasha, as they believe she holds the cure for Lamanla. Feng rallies the workers to protect their families and their fellow factory workers. Feng is about to be overwhelmed and killed when Big Daddy and his men are unexpectedly ordered to fall back. The rebel leader informs Big Daddy that no Chinese can be harmed as he needs China's support when he comes into power, since China is a permanent member of the United Nations Security Council. However, Big Daddy kills the leader and takes over, ordering everyone back to the factory to capture Pasha and kill Feng.
Meanwhile, Feng chooses to leave after the factory workers discover that he is infected with Lamanla. Rachel injects him with a serum and he learns that Chen had discovered a cure using infected patients who survived and developed immunity. Pasha is one of Chen's patients and not his daughter; she is the only surviving patient with immunity.
Big Daddy and his men return to the factory and round up the workers. Feng returns with Rachel and Pasha in a rescue attempt. The workers are saved and a helicopter arrives to rescue them. Pasha and Rachel leave in the helicopter with the other women and children, but the helicopter is shot down. The battle continues with Feng and his allies fighting hordes of Dyon Corps mercenaries and rebels, who are reinforced by several tanks. Recognizing the threat, the Chinese fleet fire missiles to destroy the tanks.
Feng confronts Big Daddy and learns that the bullet which killed Xiaoyun belonged to Big Daddy. Driven by rage, he kills Big Daddy after a brutal fight. Feng then leads the survivors in a convoy through rebel territory until they reach the UN camp. In the mid-credits scene, Feng is allowed by his commander to return to his military squadron and is shown a video revealing that Xiaoyun is still alive.
