Augustus (Samuel L. Jackson), the chief agent who showed his might in the previous episode, encountered big trouble this time. He and weapons expert Tony were chased by killers in the underground command center of the National Security Agency. Augustus suspected that these killers were assigned by radical elements within the government to deliberately subvert the national regime, so he hoped to find a suitable agent to expose the sinister conspiracy of the black sheep. Finally, Augustus found the best candidate, former special forces soldier Darius (Ice Cube), who is now imprisoned by the military police for beating his superior officer. Augustus tried every means to help Darius escape from prison successfully and persuaded him to accept this important national mission. So, Darius began to act!
