After Stephen breaks Ultra protocol during a training exercise, Jedikiah’s mysterious boss insists on meeting Stephen. Stephen grows concerned when he learns Jedikiah is unable to protect him, so he turns to John, who is only interested for selfish reasons. Elsewhere, the Tomorrow People are desperate to go topside to a party like normal people, but John and Cara disagree on the dangerous plan. Meanwhile, Stephen makes a plan to go to Homecoming with Astrid, but when he bails on her once again, she decides to find out what he is really up too.

When Stephen and Russell head out for a night of fun, they run into a potential new break-out. Stephen and Russell report back to John and Cara about the new person, but they want to keep a low profile from Ultra. Sadly, Russell learns that his dad has passed away and he is torn about whether or not he should go home. John volunteers to accompany Russell to help keep him out of trouble. Meanwhile, Jedikiah has a shocking secret that could destroy his career.

When Stephen decides to have some fun with his newfound powers, Jedikiah takes extreme measures to make sure it doesn’t happen again. After John and Russell return from their trip, John feels a strange tension between himself and Cara. Stephen tries to handle a new and dangerous breakout on his own, but finds himself in over his head and needing help from his fellow Tomorrow People.

Stephen is determined to uncover what he hopes is the key to finding his father, and crafts a plan with the Tomorrow People that involves getting inside Jedikiah's head. Meanwhile, Cara and Russell encounter an uninvited visitor in the subway tunnel base. Stephen takes a risky opportunity and snoops around Ultra.

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.
