This episode begins with a very wealthy man and his wife, killed execution style and left in their driveway. It turns out the guy made a fortune in the porn industry. This brings Grissom and the gang to look into a whole flock of peripheral characters. It's sort of a train of consciousness episode, one clue leading to another, then another. There are two teases as well. Catherine hasn't had much luck romantically in some time and Sarah is trying to cover something up. On to the next episode.
