ABC's "Zero Hour" - Season One

ZERO HOUR - "Ratchet" - Everyone is on high alert, but their search for Rachel has met a dead end. However Hank has a dream which may contain clues that will guide the team to her remote location, and, hopefully help them stop the devious plan that "Mother"/Lynch has initiated in her "New Jerusalem." Meanwhile, Theo and Vincent strike a deal that would be mutually beneficial; and Hank, Beck and Arron travel to Tajikistan with Father Mickle and the Shepherds, and are thunderstruck by what they find waiting for them. Will Lynch's final action be successful, and is this the beginning of the end of the world? "Zero Hour" airs SATURDAY, AUGUST 3 (8:00-9:00 p.m., ET), on the Disney General Entertainment Content via Getty Images Television Network.
