It is based on real life happenings in 1916 around the Jersey Shore, where sharks used to attack people. The original shark attacks occurred during the tourist season. At first, the police downplayed the danger and didn’t protect the beaches. A group of guys believed to be vigilantes entered the water and killed the shark.
