With a career-ending injury, Olympic kickboxer Sheila Stone is forced back to her small hometown, where her older sister, the local sheriff, offers her a spot on the local police force. A series of gruesome murders shakes the town when entire families are found dead; as dark secrets emerge, Sheila is on a race against time to unveil the truth and stop the killer.
With her Olympic dreams crumbled, Sheila, 28, struggles to find her place back home. She is surrounded by reminders of what could have been, stuck inside the shadow of her older sister: the golden child, the respected sheriff. But when her sister persuades her to join the local police force, Sheila's life and career start anew.
As she hunts serial killers, Sheila notices clues that others miss and offers a perspective that no one else has. She realizes she has a talent outside of fighting, and that she has a chance to embrace a new life in Salt Lake, a life outside the ring.
This is a different kind of ring, though. Sheila quickly realizes that to survive, she will need more than just her strength, she'll need a brilliance to match that of even the most diabolical killer...
Can Sheila win this match? Or will she finally lose it all?
