Who does a 9-1-1 Operator call when he has a problem? Jimmy Callahan is having a bad night in the Police Communications Center, his ex-girlfriend is stalking him, his Supervisor is threatening to fire him and the phone won't stop ringing. Jimmy feels like he is drowning, but finds comfort in the voice of one caller. A girl calls to report an attempted rape, but she is scared and has blocked her call so she can not be traced. Jimmy tries to talk her into reporting the incident, but the girl gives no information. Jimmy handles a wide variety of calls through the night including a teenage girl's attempted suicide. Jimmy's shift is finally over when he feels a hand on his shoulder, the morning dispatcher relieving him. This co-worker's voice sounds like the girl from the attempted rape that he's been talking to all night...or is it?
