A buried secret from the past is the catalyst for murder. FBI Agent Derek Reed is back in Phoenix and in charge of his new cold case team, the Legacy Unit. Plagued by visions and nightmares from his previous case, Derek questions why the dead won't leave him alone. Billy Edmonds is found bludgeoned to death in his home. His connection to high level politicians and his close friendship with Congressman Jackson, gives the dead man special privileges. When the Congressman pulls rank and puts Derek and his team on the case, Derek can't help but wonder if he is being set up. As evidence unfolds, Derek realizes this killer isn't done, placing his team in a race against time to stop him. However, when Derek searches beneath the surface of the case, a connection to a cover-up puts one of his team members in danger. Derek turns to the one person he can trust, his director. But when the evidence leads to a bigger circle of government and FBI officials, he knows continuing to dig may not only cost him his career, but the lives of those he loves most.
