The gold Caddy belonging to a legendary mobster, Mickey Dunn has been found in Lake Mead. A racketeer and extortionist, Dunn was tied to a murder in August of '77 and vanished one night, never to be seen again. After years of false sightings, this looks like the real thing.
Meanwhile, karaoke joint in town, a singer named Michael Myers delivers a killer version of "That's Life" to huge applause. A wheelchair-bound music lover in the audience, Ken Billings, calls the crooner over to congratulate him. They share a drink, then two, and end up closing the place down. Michael helps wheel Ken out to his car but instead of wheeling him to his car, he instead wheels Ken into oncoming traffic.
Grissom and Brass arrive at the scene, and Gris notices that the wheelchair's brake bolts were loosened, making it impossible for Ken to stop. They know already: it's a homicide. They figure that Ken died on impact. Ken had his wallet and id left on him- as well as a black and white photo of old Vegas.
The waitress inside the bar shows a Polaroid of Ken and Michael; she didn't know Myers previously, but Ken was a regular. Nick gets the empties Myers drank from. DNA and prints should be a snap. There's even a video of the guy singing still in the bar's player.
Back at the lab, Catherine and Greg take on the Cadillac from the lake. It's filled with 30 years of muck to be sifted through. Finally, a skull emerges from the dirt with a bullet hole straight through the forehead.
Nick checks out the photo found in Ken Billings' pocket The image is of five men standing in front of a gold Cadillac and a huge billboard for an Elvis concert at the Desert Inn in the background. Under the light of the machine, he can see that two of the faces have been crossed out.
An older man named Mason Carter leaves the hotel room of a hooker. As he's headed out, an old “woman” stops him, asking for help with her bags. He complies, only to be strangled and slammed against the wall by the woman.
Sofia and Sara arrive to work the scene. The hooker doesn't know anything; she didn't hear a sound after Mason left. It's a confusing scenario, since the old woman who registered the room, Pamela Voorhees, is an unlikely suspect. Sara checks out the bags still left in the room, surprised to find them empty. David arrives and finds another copy of the Vegas photo stuffed in Carter's mouth- this time with 3 faces crossed out. Sara figures out that the picture is a hit list.
Greg continues to process the Cadillac, pulling out pieces of a skeleton one by one, while Doc Robbins does his best to reassemble it. Greg gets a break, finding the lead .38 caliber bullet that ended the life of the skeleton. Warrick is impressed by the old-time bullet, having grown up in Vegas with the stories of Mickey Dunn. He tells Catherine of the "Ghost Rider," otherwise known as Eddie Sanchez, the motorcycle cop who pulled Dunn over as he was leaving town back in '77. No one has seen or heard from him since. Warrick thinks Sanchez was a dirty cop who took off with Dunn’s money and wants to learn more about him.
In the evidence from the car, Catherine recognizes a tie clip Dunn always wore. How would she know? She had a run-in with him at age 16. Dunn asked a hot-to-trot Catherine to meet him at 2 am outside the casino, but he never showed.
Brass arrives with the cops at the home of Johnny D'Angelo- another face in the photo, who's put in a call to the police that "the ghost of Mickey Dunn wants to kill him." D'Angelo appears at the door, spooked. He points to Mickey in the Vegas picture, explaining that he and the other guys in the picture saw Mickey take off that night in August. The four men followed Mickey out of town and cornered him.
At the morgue, Doc Robbins notices a strange flashing coming from inside an autopsy room. He finds a reporter who tries to pass himself off as a new lab guy, furiously taking photos. The guy underestimates Doc by trying to knock Doc Robbins over and escape out the door, but Robbins takes him out with one swipe of his crutch. Problem solved.
The cops head to Derek Paul's house to meet the last of Mickey's four pals. Derek's mom Iris answers, but she claims she hasn't seen Derek since he got out of jail. The cop doesn't buy it, especially since the police around back catch Derek trying to jump a fence. Sofia gets the guy in a room and tries to get the whole story, which is a little different than D'Angelo's. According to him, they never caught up to Mickey, but someone else did, and they put him and his car in the lake that night. Derek and the guys watched it sink into the water. With that, he shuts up. They have nothing to hold him on.
Derek doesn't get far. That day, he brings home some groceries to his mom only to be shot dead in the parking lot by… Johnny D'Angelo? Iris sees D'Angelo standing over the body and cries out in horror, recognizing her son's killer.
Brass goes looking for D’Angelo. But He finds him at his chicken restaurant thanks to a smell coming from the oven. It's none other than D'Angelo, with the Vegas photo clutched in his hand- face X’ed out. Hodges helps Greg with an experiment on the Cadillac, finding the gun shaped hood ornament from the original inside. That doesn't jive with the fact that a fisherman found a hood ornament exactly like it in the lake, which is how the car was first discovered.
The team is baffled by three unconnected killers offing four of Mickey Dunn's minions within 24 hours. Warrick has come up with Eddie Sanchez's police files, and presents the fact that he had family in Mexico. Maybe he stole the dough, went south and lived like a king. But the copied gun ornament throws a wrench into things.
Hodges tells Grissom that Johnny D'Angelo (the one in the oven) has been dead two days, before the Cadillac ever surfaced. And on his skin, Hodges found the makings of a mask. Grissom isn't surprised: he's figured out the scheme. One man has disguised himself as all three killers, plus one: the fisherman who discovered the Cadillac. The fisherman's given name? Krueger, Freddy Krueger. The guy had a sense of humor, naming himself after horror villains from slasher films.
Brass runs Johnny D'Angelo's credit cards in the hopes the killer made a big purchase. In fact he has- He got himself a brand new convertible Caddy. Squad cars catch up to it on the highway.
At the station, Cath sits in with Brass after unmasking none other than… Mickey Dunn himself. The skeleton in his old car? Eddie Sanchez. Dunn took out Sanchez in cold blood, and he liked doing it. To Catherine's surprise, he recognizes her, and explains only one person could have kept him away from her: Sam Braun.
Dunn collapses from a heart attack. He awakens in the hospital cuffed to a bed and confesses when he thinks he is dying thanks to a bullet he has had in his chest almost 30 years, fired by Derek Paul. But as all horror film aficionados know, the monster never dies with just one shot. "A legend is born," Mickey says. He tells Cath that he's got a week to live now that the bullet has moved inside his chest, but he gets his own surprise when Catherine shows off the very bullet he's talking about and informs him that no one knows who he is anymore.
