SEASON 4, EPISODE 416 - The team members attempt to recover a 5-year-old boy, Ethan Heller, who was in the back seat of his family's SUV when it was apparently carjacked. They initially explore the possibility that kidnappers want to secure a hefty ransom from Ethan's affluent parents. However, they soon start to suspect Ethan's father, who his wife and colleagues report has been acting odd lately, and who, per his wife's insistence, has been staying at a hotel for the past week. Upon further investigation, the agents find evidence that the father has been contacted by the kidnappers and is foolishly attempting to handle the matter himself. Meanwhile, Danny notices the telltale signs of prescription painkiller addiction when Martin becomes excessively irritable and makes rash on-the-job decisions.
