CBS last week released the promo for the CSI: Miami season finale episode "One Of Our Own."

In this episode, 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 the tip from the mole inside. When the mole is finally revealed to the entire lab, the news sends the remaining CSIs reeling.

The 30-second promo can now be downloaded at CBS.com. For those of you with slower connections, here's a full transcript of the promo video:
