Ep 22. Vengence part 2 of 2

After witnessing Nicole's murder at 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 destroyed important papers belonging to Cole. Jensen also tells him that the FBI suspects Nicole was working with Bobby Cole. Chase is livid, knowing this could never be true. Cole meets with Agent 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. Chase visits a weapons dealer he knows and purchases some heavy duty weapons for his own personal use. After a huge battle in the streets 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.
