Agent Sydney Bristow has always held her own in the traditional boy's club of espionage. In fact, she's grown comfortable in her well-earned role as respected go-to girl. But with the recent addition of her half-sister, Nadia, dynamics inevitably shift as Sydney finds herself with a new partner, roommate, and—even if unintentional—competitor. APO's mission to retrieve a mysterious biological weapon is compromised, and in the melee Weiss is infected. Driven by concern and guilt, Sydney searches for the only known vaccine—until her cover is blown and she must watch Nadia assume her field role next to Vaughn. But when Vaughn and Nadia's cover is blown, only Sydney and Nadia's collective strength can keep Sydney's "family" alive.

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.

Sydney's conscience struggles with her job, which too often asks her to work with criminals she'd much rather put away. She understands the logic—the small fish versus big fish pragmatism—but that doesn't make acceptance easier. Someone else is less conflicted and is assassinating APO's shadier contacts. Only the calling card of a black star with the number 13 in its center hints at the culprit. When it becomes clear that a highly trained—and lethal—vigilante organization is interfering with APO's missions, Sydney must put aside her empathy and help shut down the mysterious "13 Stars." But after Sydney herself is mistaken for a freelance terror agent, she worries that the mistake is not so far from the truth. And now that she's marked, both her cover and her welfare are in immediate jeopardy.

It seems the attack was a practice run for something bigger, and Sydney and Dixon must determine the real target before time runs out. There are other matters on the agents' minds too—Dixon is concerned about his son, Steven, and Sydney is led to wonder, not for the first time, what it would be like to have a "normal" family. But there's no time for wistful thinking when the saboteurs' plot becomes clear...and threatens to throw the country into total chaos.
