Assault on Precinct 13

On New Year's Eve, Detroit Police Department's Sergeant Jake Roenick, veteran cop Jasper O'Shea and secretary Iris Ferry are the only people on site at the soon-to-be-closed Precinct 13. Roenick is deskbound and abusing alcohol and prescription drugs, haunted by a botched undercover operation eight months prior that resulted in the deaths of two members of his team. Psychiatrist Alexandra Sabian is treating Roenick at the station.
