City Protective Services (CPS) law enforcement officer Kiera Cameron (Rachel Nichols) lives a quiet, normal life with her husband and son in 2077-era Vancouver. Under the corporatocratic and oligarchic dystopia of the North American Union and its “Corporate Congress,” life goes on in apparent freedom under a technologically advanced high-surveillance police state.
When a group of self-proclaimed freedom fighters known as Liber8 escape execution by fleeing to the year 2012, Kiera is involuntarily transported with them into the past. Joining with Detective Carlos Fonnegra (Victor Webster) and the Vancouver Police Department, and enlisting the help of teen computer genius Alec Sadler (Erik Knudsen), Kiera works to track down and thwart Edouard Kagame (Tony Amendola) and his followers in the present day while concealing her identity as a time-traveler from the future.
Kagame and the members of Liber8 plot to alter the past to avert the rise of a dictatorial and Orwellian corporate regime to be stopped at all costs. Meanwhile, Kiera knows that Alec Sadler will become the future corporate mogul and head of SadTech, one of the mega-corporations that dominate the world in 2077. Liber8 also attempts to alter the past by going after an agricultural chemical company Sonmanto, which through the use of genetically modified food plants created a situation in the future where independent small farms are illegal. Sonmanto, also makes a bio-weapon, in the future, for which they also sell the antidote. In season three, Liber8 steals a tanker truck full of a key chemical mixture of the precursor to the bio-weapon.
Fighting to return home to her family, Kiera finds that her presence in 2012, and that of the members of Liber8, may be no accident at all.
