Ozark Sharks (2016)

Somehow, schools of dangerous sharks have infiltrated the Ozarks lake system, and before long they become accustomed to living in their new habitat. As siblings Harrison and Molly reluctantly join their parents on a trip to the picturesque Ozarks, people get chomped, and the happy holidaymakers find themselves caught in the chaos. Now, as the underwater predators take a liking to the juicy human flesh, no one is safe in the upcoming fireworks festival. But, what has triggered the sharks' aggressive behavior? Can the remaining survivors rid the lake of the Ozark Sharks?
