The Guardsman (1931)

His disguise was perfect - did she really know it was her husband when she surrended to him...?

An acclaimed actor and his equally acclaimed actress wife, who have been married for less than a year, are already showing signs of strain in their marriage. The actor believes his wife is capable of infidelity and sets out to prove this is so. Disguising himself as the kind of man he believes she fancies (a Russian military officer), the actor woos his wife while she believes her husband to be out of town.
