The Married Virgin (also known as Frivolous Wives) is a 1918 American silent drama film starring Vera Sisson, Kathleen Kirkham and Rudolph Valentino (credited as Rodolfo di Valentina).

Mary's dour "evil stepmother", Ethel (Kirkham) is carrying on an affair with the diabolical Count Roberto di San Fraccini (Valentino).

Mary is understandably reluctant to go along with the plan, but eventually acquiesces to save her father from a life sentence in prison.

She writes to Douglas, calling off their engagement, sadly marries Roberto and retires to an unhappy existence in her home.

On a drive through the hills, she brandishes a bottle of poison and threatens to use it unless Roberto takes the next boat to South America with her.

Roberto attempts to take the bottle away from her, a struggle ensues, and the car loses control and tumbles off a cliff, killing Ethel.
