Movie Story : Meredith Hendricks is the top police officer in a sleepy town on Lake Tahoe, where nothing much ever happens. Her quiet routine collapses when Clint, a black-market exotic species dealer, is released from prison and something he smuggled into the lake starts showing up in the water. Swimmers and people on the shore quickly become prey, and Meredith and her team soon realize they are facing not one predator but an entire family of them.
