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.

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.

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.

It appears another time traveler has arrived in 2013 when the CMR network "pings" a brief connection with another CPS suit. Kiera's pursuit of the traveler leads her to her old partner, Elena - but also draws unwanted Liber8 attention, and dangerous scrutiny from Gardiner of Kiera's every move.

Sam's Birthday puts Kiera on the path to an emotional meltdown which triggers an internal diagnostic within Kiera's CMR that forces her to deal with her loss or lose her tech abilities. Meanwhile, Kiera becomes the target of a department mole hunt, when Dillon is ousted and Escher installs Nora Masters as his puppet.

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, injured during her and Brad's escape from the future soldiers, has a renewed desire to return to her son in the future. Brad reunites with the future soldiers in a bid to gain their trust and work from the inside. Alec gets revenge on Kellog by hacking into Piron which causes unexpected consequences and revelations.

Kiera and Alec risk everything to stop the future soldiers.
