After one botched assassination attempt leads to the discovery of another high profile murder-for-hire in the works, Agent Sydney Bristow goes undercover to untangle a twisted plot of betrayal, terror, and revenge. Thrown into the midst of a dysfunctional yet extremely powerful family, Sydney must determine who is trustworthy and who is out for blood. Luckily, she has some experience in this field. With time running out and political alliances hanging in the balance, the APO operatives work together to infiltrate the family and determine the target of an impending deadly attack. Unfortunately, the intended victim could be anyone -- a world leader, an adulterous wife, a group of innocent civilians, even a fellow agent -- and the clock is ticking.
