"CSI: Miami" wraps its season May 22 with an episode that will rock the crime lab to its core. Coming up:

"Rampage": Just as Horatio and Marisol begin their new life together as husband and wife, Mal Noche gang trial is disrupted when a witness helps the defendant escape during his own testimony. Now free and running from the law, the criminal orders Horatio's death -- but ends up shooting someone very close to Horatio instead. Meanwhile, a jilted lover from Delko's past wreaks havoc with anyone woman close to him.

"One of Our Own": Horatio and Delko search Miami to bring down the Mal Noche gang once and for all after the murder of someone very close to them. However, their quest is jeopardized when the Feds seize the CSI lab with the intent to close it for good, based on a tip from the mole inside. When the mole is finally revealed to the entire lab, the news sends the remaining CSIs reeling.
