Dr Ordway (Warren Baxter) is consulted by a young woman Irene (Ellen Drew) who tells him that her fiancé is suffering from bouts of amnesia after his war service.
Before very long Ordway discovers the man has been murdered by two thugs (and very nearly shares the same fate). Ordway becomes involved in a plot involving a strange house and Irene's domineering sister Natalie who went missing a few years before...
Although the plot has a few holes, this is a fine B-movie crime drama and one of the best entries in the Crime Doctor series. The action and antics of the Crime Doctor are varied and there are some good twists.
