Sandblast - S4.E7

When a Marine Colonel dies in an explosion at a military golf course, the NCIS team must investigate a suspected terrorist attack with the help from the Army Criminal Investigative Division (CID). The CIA gives them a lead to an abandoned warehouse, but it turns out to be a trap---the warehouse is set to explode. McGee uses his computer skills to break into the secret government files to uncover the terrorist cell.
