In the second two-part episode, entitled Trust, when two women are shot in a house basement, Nikki and Jack are baffled by the conflicting possible motives, while Leo faces a difficult case – proving his pathologist mentor made a mistake in evidence that imprisoned a mother for smothering her baby to death.

As the hunt for the basement women killer intensifies, Nikki and Jack are shocked to uncover a dangerous plot that threatens national security. And Leo must race against time to prove the imprisoned mother’s innocence and reunite her with her other son before he’s lost in the adoption system.
