A surprisingly fine cast was assembled for this unremarkable quickie adapted from the espionage thriller by Anthony Armstrong. Derek Farr stars as a scientist whose loss of memory alone prevents a vital secret from falling into the hands of the communists who have abducted him. Donald Wolfit was knighted the same year, but surely not on the strength of his performance here as a blustering professor. Regrettably, this was the swan song of Ella Raines, the elegant star of classic film noir titles such as Phantom Lady and Brute Force.
