Inspector Kiera Cameron loses everything she has and finds herself on a new mission when she and eight dangerous terrorists are transported from their time in 2077 back to 2012 during the terrorist’s attempt to escape execution. She takes on a new identity and joins the Vancouver Police Department in order to stop the terrorists’ reign of violence. Along the way, she befriends Alec Sadler, the 17 year old who will one day grow up to create the technology her world is built upon.

Kiera tries to find the members of Liber8 before they do more damage. Her attempts are hindered when her cover is blown and her partner on the VPD, Carlos Fonnegra, arrests her. But when she discovers Liber8’s plan to attempt to get back to 2077, she has to escape and possibly ally herself with her sworn enemies to get back home.

A scientist who is working on developing a source of clean energy is found murdered. The list of suspects leads Kiera on a journey that takes her to a precarious place – deciding between the right thing to do and the preservation of the future.

Kagame's return begins with a reset of Liber8’s agenda, away from violence and towards blending into the community. But there may be a glitch – there is the possibility that if their ancestors living in this time are murdered, they might cease to exist. A test of this theory is devised with Kiera and her grandmother as the guinea pigs.

Kagame pursues the first step of his new agenda – winning over the intellectuals and the grassroots dissenters. When Liber8 kidnaps the CEO of a major corporation, Kiera and Carlos must race an actual ticking clock to save the CEO from public punishment.

The high-stakes Union Election gives Kiera her first taste of contemporary political intrigue. But issues of trust and loyalty come up for Kiera as evidence points to Carlos in the death of an investigative reporter. Kiera will learn firsthand the lengths a person will go to get elected.

While accompanying Carlos on a routine investigation of a farmer who purchased large quantities of ammonium nitrate, a fertilizer used in explosives and agriculture, Kiera discovers that the farm is actually the home of Alec. What seemed like a routine check quickly escalates into a tense standoff.

Kiera resurfaces after the mayor is killed in a brazen assassination. She reunites with Carlos to solve the murder and also tries to reconnect with Alec, who has changed since reading the message from his future self.

Kiera races to rescue Alec from himself and preserve her own chance of getting home. Alec must make a difficult decision between solving Kiera's dilemma or his own.

Kiera crash lands her CPS flyer during a prisoner transport and is forced to work with her enemy captive in order to survive. In present day, the mystery of Kiera's murder is solved when Alec finds a way to recover the recording of her final moments from her CMR.

Kiera and Brad's trust reaches a breaking point. Carlos and Kellog come to their own realizations; Alec has a strange encounter.
