Risking it all, Alex works with Owen to infiltrate the Collaborators. When they begin to test her loyalty, Alex realizes she’s become a pawn in their plan to take down both the President and the task force.

After an impossible choice is made, a flood of new proposals shine a light on the final stages of the Collaborators’ plan. Fractured but not defeated, the task force, with the help of some old friends, work to put the pieces together before the Collaborators can enact an unthinkable terrorist attack.

It’s Alex and the team’s last stand against the Collaborators at the Constitutional Convention, where a new amendment to the Constitution threatens every American’s freedom.
