Sam and the VCTF investigate a series of fatal hit-and-run auto accidents on remote highways where the only clues are abandoned car hulks, a pattern which leads Sam to suspect a trucker (guest star Jim Wilky) who is reliving a traumatic accident from his childhood. Elsewhere: George is mugged and nearly killed in a video store holdup; Bailey feels responsible for his wayward teenaged daughter (guest star Heather McComb) when she hangs out with a rough crowd; Angel is very appreciative when John speaks to her art class
