After witnessing Nicole Stockman's murder on the order of Bobby Cole, Chase becomes a loose cannon. August pleads with his partner to follow legal avenues to catch Cole, and Captain Jensen suspends Chase after he destroys important financial papers belonging to Cole. Shoenrock claims that Stockman was suspected of working with Cole. Chase is furious, knowing this could never be true. Cole meets with Shoenrock, who is revealed to be undercover, acting as an accomplice, and tells him of his plans to execute the Colombian drug minister at the drug summit. Meanwhile, Chase goes renegade and visits a weapons dealer, purchasing some heavy duty weapons for his own personal use against Cole. After a huge battle in the streets of Los Angeles involving semi-trucks, helicopters, and rocket launchers, Chase ends up on a pier with Cole, weapons drawn in a stand-off, each prepared to take the other down . . . for good.
