A cold case reopened. A K-9 in pursuit of the truth.

When a teen goes missing from the same place where her own foster sister disappeared, K-9 handler Brynne Taylor is on the case...until she's caught in a lethal trap. Someone doesn't want her or her Saint Bernard, Fergie, snooping around, and they're willing to kill to keep their secrets. Saved by rancher Jace Jackson, Brynne reluctantly accepts the single father's help solving both cases. But they're under fire every dangerous step of the way — and eluding this killer may be as impossible as outrunning Brynne's past...
