Stalwart Republic contractee Ralph Byrd wades through a sea of stock footage in SOS-Tidal Wave. Byrd is cast as Jeff Shannon, a hotshot television commentator who goes after a corrupt political machine. When Shannon refuses to be dissuaded by bribes or threats, the villains promise dire consequences for his wife Laurel (Kay Sutton) and son Buddy (Mickey Kuhn) if he doesn't lay off. As a last-ditch measure, the head crook (Marc Lawrence) uses TV technology to scare away voters on election day by faking a devastating tidal wave which supposedly engulfs the city. The spectacularly soggy special-effects climax of SOS-Tidal Wave was lifted in toto from the 1933 fantasy feature Deluge.
