Two convicts (Howard Keel, Cyril Cusack) and one guard (Harry H. Corbett) are washed away into a flood near the small North American town of Lebanon after the barrier they were building collapses. Ending up at the flooded farmhouse of Dr. Matthews (John Phillips), the men find that the doctor is away and his daughter Elizabeth (Anne Heywood) is at home alone. Soon enough tensions rise along with the water level, especially as Peebles (Cyril Cusack) has designs on Elizabeth and Donovan (Howard Keel), appears to be innocent of the murder he was imprisoned for, and has revenge on his mind... This 1950 s classic British noir film was directed by Charles Crichton and produced by Sydney Box.
