Barracuda

The quaint seaside town of Palm Cove is home to upstanding citizens, good ol' fashioned southern hospitality… and a deadly rash of barracuda attacks. The town sheriff (William Kerwin) and a young marine biologist (Wayne Crawford) join forces to discover that the culprits are none other than the local chemical plant and its odious managers, but little do they know that the scheme runs much, much deeper.
