Prostitute Kam Kuk, Wong's childhood friend, attempts suicide several times and they inevitably reconnect during her short hospital stays, while Wong's girlfriend suffers from mysterious and sudden bouts of numbness in her arm.

Once called "Father Frank" for his efforts to rescue lives, Frank Pierce sees the ghosts of those he failed to save around every turn. He has tried everything he can to get fired, calling in sick, delaying taking calls where he might have to face one more victim he couldn't help, yet cannot quit the job on his own.
