The waters around the island of Amity are once again serene and tranquil. Past events of extreme terror are now buried deep in the town's subconscious. Yet, for one man the ongoing mental torment of these past events has left a deep psychological scar. For Chief Brody, an inescapable feeling that the nightmare will resurface once again takes him on a dark journey... forever watching, waiting... he is know by the inhabitants of Amity as... Sentinel.
This short trailer-type film concentrates on interesting projections from the subconscious, in contrast to the action sequences seen in the previous Jaws films. Making use of the original soundtrack and dialogue segments, Sentinel approaches this particular genre with new light and direction.
