When Marcella Sanchez, a senior detective in the homicide division of the Los Angeles Police Department, started investigating a homicide where a mysterious weapon was used, little did she know that she was stepping into a web of conspiracy. The seeds of this conspiracy were sown more than decade before during Operation Just Cause, in Panama.

She turns to the guiding hands of departed souls for clues. The helping hands reach out across the twilight zone to point her in the right direction. The killers are always a step ahead, and as door after door slams in her face, she has no option but to take desperate measures to uncover the tale of corruption and deceit in unexpected places.
