A call about a suicide attempt at a hotel finds a women has tried to commit suicide for the second time but she is okay. She has left a note for another resident of the hotel. When they contact the man they recognize him as a convicted felon on parole involved with some serious mob activities. The man is a recluse and refuses to talk to the woman. The officers spot a man changing a tire and ask if he needs help but he says no. A second call to hotel occurs when the manager tries to evict the parolee because he types till 3:00 am but really simply wants the man evicted. When they hear a robbery report on the radio including the car the man was changing the tire on, they report it and a description of the man. They stop at the restaurant where the woman works to check on her and tell her why her friend refuses to see her which is due to a fear of someone from the mob being after him. Detectives locate the car and ask Malloy and Reed to help identify the owner which they do. A report of shots fired at the hotel finds the parolee has lost contact with reality and believes someone is after him forcing the officers into a gun battle until he runs out of ammunition.

Reed returns from the flu and half the other officers have caught his bug. He and Malloy get drafted to double shift to night watch. Finally, Mac asks them to host a civilian police commissioner, and they get a surprise.
