The search is on, but what exactly are the folks of Fulton County hiding?

For five years, high school English teacher Sarah Baker has helplessly watched her marriage become emptier than the bed she crawls into alone each night. But a divorce would leave her in financial ruin, so she stays shackled to the husband who left his vows at the altar.

Then Sarah discovers an escape and takes the ultimate risk, only to find herself chained again—this time in the basement of a remote cabin.

When a grisly teen murder rocks his quiet northwestern town, rough-around-the-edges Sheriff Jeffrey Mills has his hands full identifying the body while facing the mounting pressure of tracking down the missing high school teacher the community is determined to find. In the blink of an eye, a heart attack sidelines him during the search, and Mills faces an impossible choice: skirt the law and lose his one chance for redemption or leave Sarah Baker to her fate.

But one thing is clear: they're both running out of time.
