It’s the biggest flood Texas has seen in years, and Carl Simmons is caught in the dead center of it. Unfortunately, he’s not alone.

HAG is the harrowing tale of a Vietnam war veteran who faces a natural disaster and finds something distinctly unnatural in the flood waters. He enlists the help of his best friend Franklin, also a war vet, who started collecting books on the supernatural  after something inexplicable happened to him in Vietnam.

Between Franklin’s knowledge, a shotgun, Carl’s determination, and a flashlight — the only thing staving off darkness after the power goes out — they might just stand a chance against the howling creature haunting them.
