Northern California pot growers bomb a car and a bus, then take over Shasta Dam in a bid to free an imprisoned comrade. It sounds like the plot to a very cheesy Grade-B thriller, but it was actually the premise for a day-long terrorist attack drill conducted by 20 state, local, and federal law enforcement agencies Wednesday.

According to an account published in the local paper the Redding Record Searchlight, the Shasta Dam scenario had the "Red Cell" pot grower/terrorists blowing up the car and bus to create a distraction and then taking over the dam. Holding three people hostage, the terrorist pot growers then threaten to flood the Sacramento River by opening the flood gates unless their imprisoned comrade is freed.
