H.G., Vanessa and Jane decide to investigate "Project Utopia" while Vanessa doesn't realize some of the people in her life are not who they appear to be.

H.G., Jane and John search for Vanessa; at the same time, Brooke moves forward in her plan to avenge her father's legacy, ultimately sending H.G. and Jane to a place where they will have to fight to survive.

H.G. and Jane find themselves stranded on the Island of Doctor Monroe. Unaware that they are an instrumental part of the doctor's research, H.G. and Jane fight for their lives—along with Dr. John Stevenson—but in the end, not everyone will get out alive.

An unwilling participant of Dr. Monroe's experiments, H.G. feels himself changing. Now on a more level playing field and finally able to take on his friend and adversary, John Stevenson, H.G. and Jane race to escape the Island of Dr. Monroe.

Wells is shocked to see a familiar face when he and Jane return to present day New York City, while Jane makes a decision that will potentially change both of their lives.

Brooke is betrayed by her brother, Griffin, when he joins forces with Vanessa to stop her from furthering their father's research. But just how far is Brooke willing to go when she forms her own unlikely alliance.

Hurt and betrayed, Dr. John Stevenson sets his sights on H.G. and moves forward in a plan for the ultimate revenge by destroying him and those he cares about forever. When H.G. learns of his plan, however, he takes matters into his own hands, finding himself in a place he could never have imagined in his wildest dreams.
