The hard-hitting adventures of tough Lieutenant Frank Ballinger, a member of the Chicago Police Department's M Squad, an elite crime-fighting unit.
An episode featuring a Chicago cop taking a bribe led to Mayor Richard J. Daley banning any television show or film from doing any shooting in Chicago at all. That ban was later broken with the filming of The Blues Brothers (1980).
Lt. Frank Ballinger:
My name is Frank Ballinger, detective-lieutenant, M Squad, a special detail of the Chicago police.
