Something in the lake... 4th of July Weekend! Time for flags, barbeques and late night fireworks. For the residents of a sleepy West Michigan community, the carefree days of sun-soaked bliss are about to be interrupted by a deadly abomination of nature...lurking in the depths of a local lake. ACIPENSER Vietnam veteran Silas Sobel loves Green Lake. He watches over the water - protects it. When he witnesses a mysterious attack on a pontoon of partiers, his claims are dismissed as wild stories. Setting out on a lone mission, he utilizes unconventional methods to capture the proof he needs. As the town slowly realizes the truth, they find themselves woefully unprepared to combat the hideously mutated monsters of Green Lake.
