On the remote Florida swamplands, an illegal animal smuggling deal goes wrong unleashing a vicious creature into the swamp with a deadly taste for teens. Meanwhile, at the Broussard family-owned Gator Shed restaurant a disgruntled customer and their whole pen of gators are mangled to bits by whatever has gotten loose and it’s not long before the crooked town sheriff pins the deaths on the Broussard family’s alligators. 

But Rachel Broussard, played by the original Buffy The Vampire Slayer Kristy Swanson, catches a glimpse of the massive shark and realises that she must take on the Swamp Shark in order to clear her family’s name, save the restaurant and prevent the unknowing folks at the upcoming Gator Fest from being torn to shreds.
