While running surveillance in an industrial section of Scottsdale, Arizona, PI Lena Jones discovers the body of a woman connected to the infamous polygamy cult Second Zion. Lena joins forces with a former polygamist "sister wife" to find the victim's killer and discovers a shocking secret: that in a society where one man can have ten wives, nine men will have none. Second Zion makes certain these possible rivals don't stick around.

In the midst of Lena's search for the dead woman's lost son, memories from her own damaged childhood surface when she is surprised by a visit from her beloved foster mother, whom she'd been forcibly parted from at the age of nine. The reunion is interrupted when Lena learns that a friend in Hollywood is being stalked by a mental patient. Lena flies to her aid, only to find that danger has followed her.
