Countdown (S01E11)

Sh'lainn foresees that everyone in the Bunker faces imminent death within twelve hours, but Rinaker dismisses her warnings and brings in an alien probe they had previously retrieved. Upon making contact with the probe, Sh'lainn becomes infected with the Iron Death, her Banshee form deteriorating due to the surrounding technology. Driven by her most basic instincts, she attempts to destroy the tech that is poisoning her. As she works to set off the nuclear core that powers the Bunker, Nick races to Ireland in search of a cure. With the threat of a catastrophic explosion looming over half of New Mexico, the Alliance is in a race against time.
