Borrowed Husbands (1924)

While her husband, Gerald, is in South America on an archaeological expedition, vivacious Nancy Burrard lightens her boredom with several flirtations. Believing her to be a widow, Major Desmond becomes infatuated with her; he meets Gerald in South America, however, and advises him to hurry home. The Burrards are reconciled, and all ends well (except in the case of Dr. Langwell, another of Nancy's dalliances, who has poisoned his nurse, Peggy Fleurette, and then committed suicide).
