M1, T10: Jack and the team investigate a father, Greg Prichard (Brett Cullen), and his daughter, Kyla (Brynn Lauren Lemon), who disappear during their regular morning routine. Greg and Kyla depart for work and school respectively, but neither reaches the intended destination. As the squad begins to uncover facts in the case, Greg's wife, Sarah (Dana Wheeler-Nicholson), is forced to confront the fact that she knows very little about her husband's past. There are no records of his existence before 1990, and financial irregularities abound. His employees identify a mystery woman with whom he may be having an affair, and his best friend reveals that the night before his disappearance, Greg offered to sell him his business. As she copes with these shocking revelations, Sarah fears that she may never see Greg or Kyla again.
