The past doesn't always stay dead and buried.

Old friends gather for a class reunion at Queen's University, but the celebration turns tragic when one of them is discovered floating in Lake Ontario. Kingston Major Crimes soon learns the death is a homicide and begins searching for the killer.

An eight-months-pregnant Detective Kala Stonechild and her new partner are assigned the case. The motive is impossible to pin down, and the team is frustrated by dead ends, including an unsolved murder in the house where many of the alumnae had lived as students. With the investigation stagnating, Stonechild travels to Saskatchewan to dig into the victim's life and finds more heartache and horror than anyone could have predicted.

The team struggles to find its footing as the past and present collide in a troubling case that spans two decades and involves untold victims.
