Plot: David awakens from a blackout to find blood and a smashed headlight on his car, and panics when he hears about a late-night hit-and-run; Tom and Ray respond to a possible kidnapping, only to find an elderly Alzheimers patient tied to a bed; as David tries to reconstruct the events of the night before, he raises the suspicions of Joel, Fearless and Ray, whose investigative abilities find the common link between the two cases.
