Unknown Person

George Lutz, his wife Kathy, and their three children have just moved into a beautiful, and improbably cheap, Victorian mansion nestled in the sleepy coastal town of Amityville, Long Island. However, their dream home is concealing a horrific past and soon each member of the Lutz family is plagued with increasingly strange and violent visions and impulses.

When the seaside community of Amity finds itself under attack by a dangerous great white shark, the town's chief of police, a young marine biologist, and a grizzled shark hunter embark on a desperate quest to kill the beast before it strikes again.
