The shooting of a homicide detective is captured on film by a mysterious figure from a second-floor window, implicating Riley Keane, an anti-gun activist and a school shooting survivor.
Riley flees Chicago for a frozen island in Lake Superior. A race to find her ensues between her secret lover - Chicago politician Finn O'Farrell - a corrupt police lieutenant, and the mysterious cameraman who extorts Riley's family and Finn. Finn's entanglement with Riley and the extortionist threatens his ambitious political career.
On the island, Riley ingratiates herself into the close-knit community, but when she witnesses both an islander's murder and another death in a suspicious boating accident, the local sheriff starts asking questions that begin to unravel her true identity.
As the sheriff and the FBI are closing in on Riley, Finn faces media pressure to reveal his mysterious role in that long ago school shooting. If the facts come out, Finn may go to prison, but his biggest fear is that the truth will forever sever his relationship with Riley.
