 In a low-risk mental hospital near Rutland, Vermont, Vincent goes berserk days before he s to be released, kills four staff, and escapes. The next morning, just before the release of waters from the local dam, a couple named Scott and Terry decide to find some money Scott s brother stole and hid years before: the water will soon cover the spot, and Scott needs the money for an operation to correct a bone disease that s crippling him. Complicating things is the fact that Scott s older brother is the local chief detective, searching for Vincent. The two stories cross when Vincent takes Terry hostage as Scott faces drowning from the rising waters.
