S.O.S. Tidal Wave is both a political thriller and one of the earliest examples of the disaster film genre. The corrupt Clifford Farrow (Ferris Taylor, A Man Betrayed), his sights set on winning the New York City mayoral race with backing from the nefarious political boss Melvin Sutter (Marc Lawrence, Flame of Barbary Coast), sees the world as his oyster.
That’s until stalwart television journalist Jeff Shannon (Ralph Byrd, Jungle Book) unmasks a system that would place the unscrupulous and unqualified Farrow into power. S.O.S. Tidal Wave remains true to its crime thriller roots until a very surprising twist. The devious Farrow and Sutter, using stock horror film footage of a tsunami-like tidal wave, try to convince an unsuspecting public that the killer wave is about to hit New York, thereby throwing voters into a War of the Worlds-type panic. Will Jeff be able to convince the public of this hoax in time to save the election?
