In 2008, a combined task group of People's Liberation Army Special Operations Forces and Chinese police raid a drug smuggling operation in an abandoned chemical facility in southern China. The leader of the smuggling operation, Wu Ji, holds one of his own men hostage while taking cover behind a section of the facility's reinforced wall. Leng Feng, a skilled PLA sniper, ignores orders to stand down and fires three shots at a weak section of the wall, penetrating through and killing Wu Ji. Leng Feng is sent to solitary confinement as punishment, but is approached by Long Xiaoyun, the female commander of the legendary 'Wolf Warriors', an elite unit within the PLA tasked with simulating foreign tactics for the PLA to train against. Long Xiaoyun offers Leng Feng a place in the Wolf Warriors. Meanwhile, in the Philippines, crime lord Min Deng, Wu Ji’s older brother, hires ex-US Navy SEAL “Tom Cat” (Scott Adkins) and his group to kill Leng Feng and avenge his brother.

The Wolf Warriors participate in a training exercise in a remote and uninhabited forested region on China's southern border. During the exercise, Tom Cat and his mercenaries ambush a Wolf Warrior squad, killing one of Leng Feng's comrades. Subsequently, the PLA and the Wolf Warriors are tasked with hunting down Tom Cat‘s squad. The combined infantry force move into the forest but are delayed by multiple traps set by Tom Cat and pinned down by sniper fire until Leng Feng manages to kill the shooter. Afterwards, the rest of the PLA force engages Tom Cat's other mercenaries, who stage a fighting retreat but are eventually overwhelmed and killed. Meanwhile, Long Xiaoyun and the other PLA commanders deduce that Ming Deng himself is also in the training area to take possession of a smuggled cache of biotechnology, which could allow the creation of a genetic weapon that could target Chinese people exclusively.

Leng Feng eventually catches Tom Cat just before China's southern border. Leng Feng is nearly defeated, but manages to kill Tom Cat with his own knife. Medical personnel claiming to be from a PLA relief force arrive, but Leng Feng recognises the wrist tattoo of a medic and realizes that they are Min Deng's men in PLA uniforms. He attacks them, eventually holding Min Deng at bayonet point on the very edge of the Chinese border. Min Deng's paramilitary force approaches from the other side of the border, but so do the rest of the Wolf Warriors and PLA soldiers. Min Deng's force retreats, leaving him to be arrested.

The script went through 14 drafts over seven years.^[5] In order to portray more realistic combat scenes, the movie used five missiles (each at a value of one million yuan), more than 30,000 rounds of ammunition, and a variety of Chinese active military aircraft, including the Chengdu J-10, Harbin Z-9, and CAIC Z-10. In one large battle scene, 32 active tanks appeared in the same shot, including a Type 96 tank.^[5]

In order to prepare for the film, with the support of Chinese PLA Nanjing Military Region, Wu Jing trained for 18 months at a camp in Nanjing Military Region.^[5] On the first day of shooting, it was the hottest summer in Nanjing's history. The temperature was up to 49.8 °C, making 5 extra actors suffer from shock.

Most of the film was made on location in Jiangsu province, at sites including Nanjing and Sun Yat-sen Mausoleum.^[5]

The film had an overall rating of 6.8 on the Chinese review site Douban as of August 2017.^[8] Variety magazine wrote: "To a layperson's eyes, the military exercise does look authentic, and the cross-country skirmishes are ruggedly watchable on an acrobatic level. Yet it's impossible to overlook the inanity of the plotting".^[9]
