While covering up Lt. Skinner's sudden disappearance, Linden and Holder are assigned a new case: the brutal murder of an entire family with ties to a military academy.

Sarah and Holder develop opposing theories on the case, but find it helpful to look at the Stansbury mansion from a different perspective. As Kyle re-acclimates to St. George's and the cadets close ranks, Colonel Rayne asserts her dominance.

The Detectives start digging up Stansbury family secrets after their bodies are buried. Kyle finds a kindred spirit in Colonel Rayne. Sarah makes a bold play to cover her tracks and says goodbye while Holder goes off the rails.

The investigation leads Sarah and Holder deeper into the world of Seattle's most privileged. Kyle eschews a St. George's tradition and becomes afraid that his life is in danger. Sarah impulsively burns a bridge.

Reddick has managed to locate Skinner's body in the lake, and along with it the bodies of all of his young victims. Sarah and Holder watch helplessly as Reddick inches closer to finding out the real truth.
