The team investigate the theft of scratch-off lottery tickets, but the stakes are raised when one of the culprits killed at a botched robbery turns out to be a former lottery winner.

Jack and his squad search for a young man, 17-year-old Andy Deaver (Jared Hillman), who was last seen by the charismatic headmaster, Graham Spalding (Conor O'Farrell), of Spalding Academy, the private boarding school Andy attends. When Andy is reported missing, Jack immediately suspects the headmaster. Spalding is a former veterinarian with no credentials for his current job except that his father founded the school. And it appears that his relationship with Andy, as well as with other boys in the past, was unsavory. As Jack gets closer to implicating Spalding, he fears that he won't be able to get enough information from Spalding in time to find Andy alive.

Jack and his squad search for a toddler, Abby, who was snatched from a park playground while playing with another child. Abby is the daughter of prominent New York Assistant District Attorney Angela Buckman (Marin Hinkle) and her college professor husband, Matthew (John Mese). As the investigation proceeds, clues implicate suspicious people in both parents' lives. But when none of the suspects proves to be the culprit, and a ransom demand is made, the team members suddenly realize that they are focusing on the wrong aspect of the case.

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.

Jack is distraught and defensive when Chet Collins (recurring guest star Charles S. Dutton), whose son has been missing for 6 years, decides to search for him on his own because he thinks Jack has given up hope of finding him. Feeling guilty over his failure to recover Collins' son, who was 2 years old when he disappeared, Jack kept the case active despite fearing the worst. However, after Collins comes in with another clue, Malone becomes angry and tells him that the case will never be solved. The team gets involved when Malone fears that Collins will do something desperate to finally get his child back.
