A rising dam threatens to submerge a small town in this gripping disaster film. When the Rutland Dam's water level reaches a dangerous high, a terrible accident occurs, and architect David Powell (Joe Lando) realizes the dam is going to burst. Powell tries to convince his son and the mayor (Michele Greene) to evacuate Rutland before it's under water, but a corrupt construction company president (Bruce Boxleitner) is determined to discredit him.
