Prison is no place for a detective . . .
Helen Grace was one of the country's best police investigators.
Now she's behind bars with the killers she caught.

Framed for murder . . .
She knows there is only way out:
Stay alive until her trial and somehow prove her innocence.

Locked up with a killer . . .
But when a mutilated body is found in the cell next door,
Helen fears her days are numbered.

A murderer is on the loose.
Now she must find them.
Before she's next . . .
