Church goes to visit a man named Miller, who designs and builds bombs for perspective clients, selling them over the internet.
On arrival Church goes through the fellows place trying to dig up any evidence of fraud involving credit cards when he accidentally stumbles across a time-bomb tied into the guys computer. He response by bringing in bomb squad to disarm it and one on them sends in an electronic robot, which he controls by remote. The only problem is in trying to disarm the bomb it causes the robot to malfunction and come running back out of the house sending everyone diving for cover. The bomb later turns out to be a fake.
Back at the factory, Danni stumbles upon Stonie's secret when she discovers a packet of steroids in his draw and queries him over it when Mac walks in and calls him into her office, discovering that he has been using them without a perscription. She later adds that if he has any more that he should get rid of them.
Later on Church is seen talking to Miller when three gunmen in balaclavas come racing in with guns drawn and start firing at them. He later learns that not only were they police officers involved in the shooting, but that they were also tied in with Assistant Commissioner Jim Courtney who was conspiring with Stone on a plan to do away with Miller, reasoning that he (Miller) was the one behind the Bill Hollister car bomb attack and didn't diserve to live.
Courtney then got on the phone with Miller bating him to build him a bomb within a two-day deadline and Stone later found himself being recruited to take on the roll as a sniper to do away with Miller.
Later on in predictable Stingers fashion, Stone found himself borking at the situation and we got to see him do some major butt kicking as he and the Assistant Commissioner tussled it out. And we also finally got to see him kick his steroid habbit.
