Having escaped Pretty Lake, Harrison and his sister start pushing Chuck for whatever plan he has now that they have escaped. Then tension is high but they don't get to argue for long because a military van shows up in the middle of the road and a sniper shoots Sam in the head, causing her body to collapse on the horn. Chuck is quick to push Sam's body in the back with Harrison, turn the van around and head back to Pretty Lake.
The exit Wiley and Adam used to escape Pretty Lake is closed over. Liam Cullen shows them his license and says that he took a vaccination to prevent him from getting sick. It seems that Liam's goal is to come up with a cure for the residents of Pretty Lake.
Chuck drives back into Pretty Lake, apologising to Harrison repeatedly for the death of his sister.
Adam decides to search Liam's bag and Liam explains that the must take a vaccine twice a day. Adam is immediately suspicious at the very idea that they might have to take an injection, given that the last shots they were offered were deadly. When Adam hears helicopters, Wiley, Adam and Liam rush outside. Chuck also sees the helicopters and increases his speed once he realises that they are headed to Pretty Lake. The helicopters drop off packages at the center of the town just as Chuck, Adam, Wiley, and Liam arrive. Liam is quick to claim ownership of the packages and this naturally raises the distrust of everyone. Adam in particular is concerned that the package could contain a bomb. Against Chuck's advice, Harrison decides to open the package because with the death of Sam, he's seen where Chuck's leadership leads to but Chuck stops him. Chuck refuses to give in until Wiley and Adam explain that they both got out and are contagious. Liam argues that he's the only reason that everyone is still alive and tells them to trust him.
Ronnie wakes up when Renee throws the gun she stole from him along with some food on his bed. Ronnie isn't particularly welcoming and asks Renee to go and she explains that it was a crime of convenience. To smooth things over, Renee offers up sex which Ronnie is more than happy to accept.
With Adam holding a gun to him, Liam opens the package which contains his lab equipment.
It seems that Ronnie has forgiven Renee, so she uses his goodwill for information about her missing brother Eric. Renee thinks that Eric may have wandered into town and since Ronnie knows people, he would be able to get answers. On the back of the picture of Eric, is a map Ronnie is to use if he finds Eric. With that, Renee takes her leave.
Gord stares at the carcass of the dead cow. Gord gets to work butchering the cow and hanging it up to blees. He packs the meet up in blue coolers and stores them in his truck. While he's in the kitchen washing the blood off his hands, the truck is stolen. Gord chases after his truck with a rifle but doesn't shoot.
Harrison has clearly gone over the edge and is playing paintball in the house. Luke tries to talk him down but Harrison is only stopped by the arrival of Frannie.
Ronnie makes his way to the bar to ask about Eric. He hands Mark and Melissa a picture of Eric but of course neither of them claim to have seen him. Melissa suggests that Ronnie check out Harrison's crew. The minute Ronnie leaves, Melissa tells Mark to ensure that he's cleaned up his mess.
Liam is ready to run tests and so Adam is quick to volunteer but Liam needs someone who is actually infected. This is news to Riley and Chuck, who learn for the first time that Adam is immune to the virus because his father ensured he would be. Chuck gives a small blood sample and Liam compares it to his own. Yes, it's Liam the Science Guy Time.

This is all really amounts to filler on what is already a boring episode. The whole thing is implausible anyway so way ram in some pseduo science? Liam then asks for volunteers for the first shot and Adam grabs the needle and injects Liam with it. An angry Liam calls it a mistake, saying that the vial represents a single life which Adam wasted. Adam is not convinced, pointing out that the last cure they were offered killed people.
