When a San Francisco Police Department storage site is robbed, seventy-two guns go missing, setting off a wave of gun-related deaths in the city.
Brought in to head up SFPD's Computer Forensics Team, Mei Ling discovers something at the scene that doesn't make sense--a hacking device.
The police have no leads and no one can find the connection between the shooters.
Convinced the device could be the key to the case, Mei begins to suspect that the burglary was only a distraction for the real motive.
When the bullets start flying through the window of her own home, Mei knows she's on to something. Now it's a race against time to identify the hacker.
Before she becomes the next victim sent to the grave.
