The Working File

Wow.   After watching this episode, I’m stocking up on duct tape and bottled water.

The team and their families find themselves in the middle of a poisonous gas attack.  Chlorine is being released to the air through the water supply.  Everyone in their town has to get indorrs, seal off vents, windows, and doors, and hope their air hold out until the attack is ended and the gas disperses.  Many people die.

We see each team and family member react. Jonas is out jogging and notices a handful of dead birds in the road. Mack and Bob are at a girls soccer game with one of Mack’s girls, Kim and Molly. Tiffy is handling detention duties at the high school, and Tiffy and Mack’s other daughter is swimming in the apartment complex pool. Red Cap is not seen in this episode.
Jonas puts cloth over his face, and continues running. He finds some people, already dead, on his way. Eventually he makes it back without incident to the fake airplane company, where new team member Sam (Whiplash). From here, he will direct and begin the Unit’s response to the attack. Because the facility has its own generator and airtight defenses, he and Sam are pretty much fine.
Bob and Mack herd their families and several civilians back into their apartment complex, although Mack has to detour into the pool area to rescue his daughter. After their attempt to set up several safe apartments fails, several groups of people congregate in a single apartment.
Grey was driving when the attack begins. His first sing of trouble is a multi-vehicle pileup blocking his way.
He gets out of his car, covers his face, and starts looking for survivors. He finds a father and son still holding on and gets them into the back of the airtight container truck. It’s a tight space, and as other group of people arrive, the father starts getting uptight about sharing the air, and even locks Charles out of the truck in one instance when he goes out to help another arrival. Grey breaks the lock, gets himself and one more survivor into the truck, and puts the father into a choke hold, just long enough to put him to sleep without harming him.

Back in the apartment, Mack and Bob argue over whether to try to reach Tiffy at the school, and also how they might get out to reach their base. A tip that another apartment resident is a scuba enthusiast leads them to break into his apartment, where they find two working air tanks. Along the way, they see some people who left the apartment, against their advice, to search for loved ones.
Back in the apartment, they are running out of bottled water, which apparently purges the chlorine from your system. The tap water is worse than useless because it is contaminated. tensions are starting to rise in the apartment, although they never get quite as bad as in the truck.

Tiffy really shines in this episode. She seals off the classroom with her three detention students, and heads off to find and shut off the air conditioning controls. Along the way, she has the presence of mind to grab some bottled water in the teachers’ lounge, and rescues a girl near death in the hallway.
Mack and Bob stop by to check on her on the way to the base, where they team up with Jonas and Sam to plan their counterattack. Sam monitors the plume and wind details to pinpoint the probable point where the terrorists are inserting the chlorine into the water supply. I guess, but I do not remember it being mentioned, that this is the Hill 60 of the episode title.
The actual fight is minimal. The unit captures one terrorist and kills the rest. On their way back they pinpoint Grey’s cell phone location, and rescue him and his civilians in the truck, where everyone is passed out and on the verge of suffocation.

Back in the apartment, Kim feels compelled to go outside to alert the national guard of their presence in the apartment. After an elderly woman offers her small oxygen tank, she does so, and eventually returns with the Guard, although they all arrive after the team has stopped the threat abnd the gas has dissipated.
Afterwards in the debriefing, they discuss how the men they found at the water plant had the tattoos of prison based white supremacist groups, but they also determine that they were patsies, noting thattheir equipment would not ave continued to protect them for long, so they would have died even if the Unit hadn’t found them. It is not clear whether this means white supremacists aren’t behind the attack or not. In a surprising move, Ryan announces that the response to attack, which was directed at the Unit and their families, has put the conspiracy on the run so they can move back to their original base in Missouri and reunite with their families. This seems odd, given that they still do not know who is behjind the whole conspiracy and there does not seem to be any reason to believe it is completely abandoned, but that is pretty much how the episode ends.
Overall, this was a thrilling compelling episode, and I thought made the best use of the team’s families in a long time.
