After Cragen is accused of murder, the team works secretly around the clock to defend him. Meanwhile, when Amaro also becomes implicated in the scandal and his personal life falls apart, he refuses to go down quietly.
The series follows smart, capable and by the book Grace Narayan (Anjli Mohindra), who was flying high as an inner-city police sergeant before being forced into a 'punishment posting' on the small, antiquated island of St. Jory. Confronted by the forgotten and unsolved case of missing teenage boy Cai, Grace quickly discovers that she must overcome scarce evidence, extraordinary local characters, and the island's strange cult history to uncover the truth.
