Fiercely protective single-mom Meredith Hendricks happens to also be the best cop in her quiet town on Lake Tahoe. When a black-market exotic species dealer named Clint, is paroled from prison, something he let loose begins to make its presence known. Swimmers and land-lovers alike begin to become part of the food chain at an unbelievable rate. Meredith begins to investigate these brutal attacks and discover that they're not just hunting one eating machine, but a whole family of them. After a documentary crew is devoured when they don't take the threat seriously, it's up to Meredith and the unlikely hero, Clint, to stop the most dangerous thing on the planet: A mother protecting its young. Not everyone will make it out alive, but those who do will never forget this summer at Shark Lake.
