High Treason (J. Arthur Rank; Pacemaker) wrings a good deal of bang-up drama from a spy plot in which enemy agents conspire to blow up England's strategic power plants. The picture is a solo effort of Britain's talented Director Roy Boulting, who, with his twin brother John, made the taut 1950 thriller Seven Days to Noon, about a demented atom scientist's attempt to destroy London.
Though played on a larger stage, High Treason is not quite so dynamic as Seven Days to Noon. The screenplay sometimes bogs down in low melodrama, and the pace lags now & then for wordy political digressions....
