In small town Rancho Rosa, locals spouses Selby (33) and Jana Vickers are found stabbed in their car. It's their 1995 high school class's reunion, which they never attended. Selby was a social leper since he confessed a cruel prank at Derek Logan's expense 15 years ago. And he was involved in blackmail. Patrick works out the past and abuses Rigsby's own secret to force him to help set a trap.
