Alex Tully is a 35-year-old landscaper with a dark past. His wife Kathryn goes missing, leaving him distraught. However, when Kathryn's anniversary present to Alex begins to ring, he rips open the package to find a cell phone. The mysterious call plunges Alex into the race, baiting him with the prospect of seeing his wife again. The catch, however, is that he has to embark straight away, and if he ever hopes to see her alive he will not notify anyone about where, or what he is doing. Meanwhile, the local police consider Tully a prime suspect in the disappearance of his wife, and subsequently view his sudden departure as overly suspicious behavior.
