Kiera Cameron (Rachel Nichols), a Vancouver City Protective Services officer, is transported from the year 2077 to 2012 when eight ruthless terrorists, known as Liber8, attempt to escape execution through time travel. With the help of 17 year old tech genius Alec Sadler (Erik Knudsen) and VPD officer Carlos Fonnegra (Victor Webster), Kiera must survive in our time period, and capture Liber8 before they can alter the course of history and change the future.

When Jake Green returns to his Kansas small-town home Jericho, where his dad Johnston is mayor, everyone is preoccupied with petty private business and family matters, but that changes drastically after a completely unexpected explosion. It soon becomes clear there has been a nuclear attack, but neither by whom nor on which scale. Suddenly life in Jericho, and as the inhabitants gradually discover all over the disintegrating USA, becomes a more primordial struggle for survival, where unexperienced dangers, primitive as well as technological, have to be weighed against pressing primal needs, such as food, fuel and self-defense against plunderers, invaders and even each-other. Jake, whose private story like that of other main characters slowly becomes disclosed to us, proves extremely resourceful and a smart hero.
