Blue Demon is a 2004 American direct-to-video science fiction horror film directed by Daniel Grodnik and starring Dedee Pfeiffer, Randall Batinkoff, Danny Woodburn, Josh Hammond, and Jeff Fahey.

Six weeks later, General Remora is sent to oversee the operations, with Nathan, Marla, and the project's financer Lawrence Van Allen giving a demonstration of the sharks' abilities.

Meanwhile, a fisherman who was fishing with the father and daughter kills one of the sharks with a harpoon gun after it attacks a couple in the lake.

They go back to the lab to confront him, although Remora arrives, and reveals that he was the one who created the shadow program; Avery is his accomplice.

He's doing it in order to increase the U.S.'s security by making them more aware of terrorist matters, using Red Dog as an asset to place bombs in various areas.

They discover that Red Dog is carrying a Russian plutonium bomb, set to detonate near the Golden Gate Bridge.
