In XXX, Vin Diesel plays Xander Cage, an extreme sports nut who stages high risk stunts and broadcasts them on the internet. His activities bring him to the attention of the National Security Agency, who blackmail him into service as a secret agent. Soon, Xander is despatched to Prague where he infiltrates an underground organisation named Anarchy 99. There he uncovers the group's fiendish plan for a doomsday scenario using a deadly biological weapon. He also finds the time to fit in some adrenaline-pumping stunts and to get up close and personal with bearded Eurobaddie Yorgi's (Marton Csokas) girlfriend Yelena (Asia Argento).
