Crashes, gunfights and mobsters abound in this Season 7 finale of CSI: Miami.

Ivan Sarnov is eating in the jail cafeteria when he collapses and is taken to Dade General. The ambulance is cut off by a car and then pushed by an SUV into the path of an oncoming train, which hits the ambulance, setting it ablaze. An who rises from the ashes? Sarnov. The police arrive and a shootout ensues. Sarnov runs off, and the officer is left for dead on the ground. When Horatio arrives, one of them tells him that he has a daughter and in typical fashion, Horatio offers to take care of her.

Horatio is on a mission to find the owner of the car. He goes looking for Sarnov at a bar, where his number two, Gregor Kasparov, claims to not have seen him. Yelina comes over and kisses this guy and then throws a drink in the face of Horatio, who has her arrested.

"Your curtain is down on your country Caine. The future is ours," says Gregor.

"The show ain't over," says Horatio.

Of course, CSI: Miami Yelina is undercover again. She tells Horatio what she knows about a gun shipment that was intercepted from the Russians by undercover agents. The deal was set up by Sarnov from the inside. The Russians may be planning on stealing back the shipment.

Eric and Calleigh show a picture to the owner of the car, Anthony Green (played by Brian Austin Green), at the scene of the accident. He admits that it's his car, but he says he was carjacked and that he had reported it. He says he was at work all morning, showing a house to a client.

Sarnov was shooting in every direction at the scene, so Natalia and Ryan wondered if the guys in the cars weren't trying to help him, but rather trying to kill him.

They track down the owner of the SUV — Jacob Yarovski. Under questioning by Tripp and Horatio, he admits that the guys were mad because Ivan messed up the gun shipment. They poisoned him in the jail to get him out, but wanted to publicly kill him.

Calleigh zooms in with the computer to a picture of the guy driving the stolen car, and it's Alexander Sharova, Eric's dad. She tells him and he gets mad. She doesn't want him to contact him.

Yelina goes to meet Gregor, who takes her to a place where a man is digging a shallow grave. He says it's for Ivan, and he wants her to kill him to prove her loyalty. He wants a body in the grave by sundown — "his or yours."
