A surprise visitor throws life in the post-apocalyptic settlement of Whitechapel into chaos, heralding the return of Mark, the exiled former leader of the FreakAngels.

Freed of Mark’s psychic control, newcomer Alice helps the FreakAngels defend Whitechapel against the biggest raid they’ve ever faced, and earns herself a place among them.

Moved to protect a group of desperate refugees, Connor and the other FreakAngels stretch Whitechapel’s resources to the breaking point. Meanwhile, FreakAngel Arkady suffers haunting visions of a ghastly murder within the settlement.

Afraid of losing the trust of Alice and the other citizens of Whitechapel, Connor makes a desperate attempt to regain their trust by revealing the FreakAngels darkest secret to Alice.

When it becomes evident that FreakAngel Luke is responsible for the murder of a citizen, the conflict causes deep divides within the group. Meanwhile, Alice struggles to decide whether or not to reveal the FreakAngels’ secret, Arkady’s psychic visions become increasingly unsettling.

Pushed over the edge by the continued violence and the shock of the FreakAngels’ secret, the citizens of Whitechapel try to flee the settlement. Meanwhile, Luke goes on the run, drawing fire from hot-headed Jack. Mark returns to Whitechapel.

Mark shows Connor how powerful he’s become, but he’s no match for the rest of the FreakAngels -- or is he? At last, Mark reveals his true intentions, driving a wedge between the FreakAngels’ ranks.

Connor risks everything to stand up for what he believes is right, but it’s Arkady who truly takes the group by surprise. The FreakAngels must decide what sort of future they want for Whitechapel, and humanity as a whole.
