A domestic terrorist group, led by the ruthless Vance Galvin, plots to assassinate the U.S. president and everyone in the line of succession during the State of the Union Address. Their goal: to install their own "Designated Survivor" and remake America into a white, Christian nation.

As Galvin amasses weapons of mass destruction to exact revenge for Waco, Texas, Tim becomes a target. When Allie is kidnapped, Tim must enlist the help of a haunted Vietnam veteran once linked to Galvin. Together, they must stop the attack before the government falls into the hands of extremists.

Designated Survivor is a gripping political thriller that weaves personal loss, terrorism, and patriotism into a fast-paced story of survival, sacrifice, and courage.
