Three pupils of father Leo's prestigious Catholic high school St. Angelo's die from drug use at a party, hosted at home by classmate Caitlin Breyer.

When known dealer Wayne Foster is arrested, after denunciation by school pusher Billy Romero, identified with some help from the archbishop after a talk with alumnus Frank, the lab shows the rest of his batch is clean. Danny must find a more personal motive, especially after his victim survives another attempt on her life, now by car.
