With the possible return of Roger on the horizon, everyone is concerned about the consequences if The Founder were to find out. Stephen now knows the truth about the machine The Founder has been using him to train in and needs John and Cara’s help to destroy it. Meanwhile, Russell and other Tomorrow People have lost hope they will ever find The Refuge and choose to head out on their own.

When the Tomorrow People learn the truth about the serum they were injected with, Stephen and Cara attempt to buy time for Jedikiah while he tries to create a possible antidote. Growing impatient, Russell and the other rogue Tomorrow People make a rash decision to sacrifice Roger to Ultra for their own safety. Meanwhile, John is having a hard time figuring out his new role and the only one he can turn to for advice is Astrid.

Russell realizes his alliance with The Founder was a mistake, and tries to make up for his decision by saving Cara from an Ultra ambush. Stephen understands that he must be the one to stop The Machine and the extermination of humanity, but he fears he may be too late. Russell offers up a plan to help Stephen, but he is going to need everyone’s help, including John and Astrid, if they are going to have any chance to survive. Meanwhile, Jedikiah offers John an interesting opportunity that could have them working together again.
