After the murder of the parents, siblings Justin, Abigail, and Zoe work as F.B.I. agents trying to bring justice to families, aside from the fact that they never got their own justice. But what happens when Abigail falls for her married co-worker, or when Justin's anger issues cause probelms on the crime scene, and what about Zoe's post traumtic stress disorder. Will the siblings be able to protect those around them, or will they end up destroying the ones they love.
