Not long after he begins digging into the victim's work, another co-worker turns up dead, convincing him once and for all that something sinister is brewing behind the cubicle walls. His investigation leads him to a mysterious woman name Leah, who pushes him to entrust her with the information he's collected about his dead colleagues.

Realizing they are close on the trail of a dangerous criminal, the pair race to expose a data theft ring before they become the killer's next victims.
