After years of suffering through lookalike MGM musicals (at least, that was his complaint), Howard Keel was able to sink his teeth into a dramatic role in the British Floods of Fear. Serving a life term for murder, Donavan (Howard Keel) breaks out of jail with sadistic convict Peebles (Cyril Cusack), taking along a wounded guard (Harry H. Corbett) as hostage. It is Donavan's intention to exact revenge against the man who framed him, but this will have to wait: a driving rainstorm is threatening to precipitate a raging flood. Taking refuge in the tiny house owned by the terror-stricken Elizabeth (Anne Heywood), the convicts and their captives nervously wait out the storm. Slowly, Elizabeth and Donavan are drawn to one another, while Peebles threatens to erupt into a fit of homicidal rage at any moment. When the flood reaches the danger level, Donavan performs several self-sacrificial acts of courage, prompting Elizabeth to try to save him from ruining what's left of his life.
