With eighty-seven hours remaining until Army evacuation and emotions running high the group are solemn except for Megan and Aston who both dreamed that they were eaten by Zombies. Jonas attempts to comfort Amena whilst talk turns to who will go on the next mission. Sometime later, Jordan and Nic, two new Survivors are seen approaching the northwest side of the Shopping Village but are blocked by a disused checkpoint which has a smartphone that when rung alerts the infected. Nic takes the phone to distract the Zombies giving Jordan the chance to unlock the cage and reach base camp, however exposure to the phone has started a countdown in which Nic has four hours to be cured otherwise he'll become infected. As the Survivors in base camp watch on, Jordan bangs on the door though Jackie is skeptical about him. After completing the Army approved tests, he is welcomed.
As the Army scan for preventative antibiotics, Amena and Jackie bring Jordan up to speed about the situation. With the Zombies focused on Nic, the rest of the area is clear and with the antibiotics located, Leah and Sara head out to retrieve the medicine but are given the option to spend the money on alcohol instead. The group decide on the antibiotics. With time running out and the hoarde growing in number around Nic, Jackie and Jordan head out to rescue him. Jordan is tasked to divert attention away whilst Jackie administers the medicine, Nic is rescued and joins the group and he settles in. He then announces he is deaf, but is able to communicate via lipreading. Jonas and Amena head on the next mission to retrieve more food from a morgue but must act dead as a group of Zombies scour the area, upon returning to base, Amena and Jonas are both sick.
After settling down for their evening meal, the group decide by drawing the lowest numbered playing card to determine who goes on the next mission with Megan and Aston being selected though Megan is starting to show unusual behavior. As they race back to base, the Army locate a new survivor behind the approaching Zombie hoarde following Aston and Megan, as the Survivor screams for help, Aston goes back and rescues her. After being tested, she introduces herself as Tasha but when she is questioned on her missing backpack, she claims to have left it in a caravan and she ran straight through a group of Zombies. Amena tells Megan and Jordan that she doesn't like Tasha as she is behaving erratically. Jackie feels nervous about Tasha and suggests to Jonas that someone stay up all night to keep an eye on her whilst Amena suggests that Aston and Megan begin a romance which they both laugh off. The episode closes on Greg James telling the audience that Tasha's backpack contained a 5G smartphone which she had used previously and her exposure to it has endangered the entire base.
