A tough Washington, D.C., police chief struggles to shape up the demoralized department and reduce crime. `Mannion is an equal-opportunity abuser,' said the actor who played him, Craig T. Nelson. `As long as you're doing and implementing what he feels is correct, then you're on his team. The minute there is any kind of disallegiance or betrayal or ineffectiveness, you get written off really quickly.' The series is based on the experiences of ex-New York deputy police commissioner Jack Maple.
