Tattooed. Head shaven. Buff to the max. Attitude to spare. A walking advertisement for anti-authoritarianism. And like the letter that begins his first name (and is emblazoned into the back of his neck in triplicate by ink-and-needle), extreme in every way. Xander Cage (Vin Diesel) is XXX. He makes his questionable living by selling web videos of his outrageous, thrill seeking exploits, whether parachuting out of a stolen car as it plunges 700 feet off a bridge, or other renegade activities which invite maximum adrenaline flow or, perhaps, a very early grave. Xander has a coterie of friends and admirers in their death-defying subculture, but after his umpteenth tangle with the law, his world is about to take the most extreme detour yet. For what Xander doesn’t know is that he’s been “scouted” by Agent Augustus Gibbons (Samuel L. Jackson), a veteran agent with the National Security Agency whose tough attitude and scarred face mark him as a grizzled but determined warrior for America. Gibbons and the NSA are facing a desperate situation in distant Prague, where their undercover operative has been killed by a gang of cutting-edge thugs calling themselves Anarchy 99, headed by the brutal ex-Russian Army commander Yorgi (Marton Csokas) and his beautiful but hardened girlfriend, Yelena (Asia Argento).
