Swamp Shark (2011)

After a botched attempt to secretly transport an ancient species of shark, a team of unscrupulous animal smugglers accidentally release the voracious man-eating machine into the warm waters of the Louisiana bayou. Now, only one short week before the popular Gator Fest, Sheriff Watson blames the local restaurant owner, Krystal Broussard, for the gruesome death of a resident, refusing to believe that a hungry shark is patrolling the river. But, the swift underwater beast is on the loose, and humans are his favourite prey. Who can stop the ferocious Swamp Shark?
