The Day They Raided the Knights - S4.E16

When budget cuts hit CONTROL, 99 is on the list of agents to be laid off. She then finds a temporary job at a trading stamp redemption center, which also happens to be a KAOS munitions drop that is about to begin distribution of their latest weapon, a stereophonic pistol. 99 finds out what is going on and informs the Chief, but is captured before she can give the location. The Chief and Larabee eventually find the location, but are captured themselves. It is now up to Max to find and save them.
