7 - 4: Roll Call

When an officer calls for help but fails to give his name or location, it results in a frantic search for the missing officer. The dispatcher helps by doing a roll call of all the known officers on patrol at the time of the call, while Reed and Malloy assist in the search. A motorcycle officer is the one who is missing, eventually leading their comrades to a parking garage and an armed hostage situation.
