12-year-old Mike Gerard goes missing, after his mother witnesses a man forcing him into a car. Martin, who is jogging in the area at the time, chases the car for several blocks, but loses it. Initially the team suspects that Mike has been taken by a pedophile, but when Martin's photofit leads them to discover the identity of the man who took Mike, they suspect that he may actually have no intention of harming the child, but instead is using him in an attempt to undo a tragedy that occurred to his own son exactly a year ago.
