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 must race against the clock when she realizes that in her timeline, today is the day that terrorists bomb a building killing hundreds of innocent people. As she tries to stop the imminent bombing, Liber8 kidnaps her trusty sidekick Alec after he realizes his stepbrother Julian is under their sway.

Kiera and Carlos work to free hostages including Dillon, taken prisoner by Liber8 at a television station. Meanwhile, Kellog and Alec's business alliance falls apart, turning the two men from partners to adversaries.
