Elvira Scala, the new chief of police in Chicago, walked into a department which after years of good policing, is inexplicably unable to solve its growing levels of crime. Worried about poor clear-up rates and the increasing numbers of unexplained murders, she invites homicide detective Lt. Kristina Maxwell to Chicago on a six month secondment. It is an invitation that Kristy's own Chief accepts with alacrity, as recent newspaper revelations about Kristy's sexuality, makes life temporarily more difficult for her. In Chicago, Kristy joins forces with Elvira and her boss, the aging but engaging, assistant superintendent of police, to defeat an ever more powerful, international criminal element. In doing so, she is faced with solving the murders of several young, dynamic lesbians even as plotters attempt to demolish her and Elvira, whichever way they could.
