Blanche, the charming wife of Mr. Berni, a lawyer, is fond of society, and when her husband devotes all of his time to business affairs, she is much in the company of Robert Martin, a handsome, carefree fellow. The affair is causing considerable comment, when her brother, Paul, becomes alarmed. After vainly trying to convince her husband of the impending danger, he decides to save his sister himself. He obtains an introduction to one of Robert’s old flames, a well-known actress, who is easily persuaded to write a note to Robert, requesting him to give her a farewell dinner, for old time’s sake, at a fashionable hotel. Paul then gains Blanche’s consent to dine with him at the same place, the same evening, where they can see without being seen, the party at the other table. The farewell banquet proves a hilarious affair and ends in a loud quarrel. Thus Blanche discovers Robert’s true character, and realizes that if she had yielded further to his attentions, to what depths she might have fallen. Without a word she leaves the table and goes straight home. In great despair over her past folly, she seriously considers taking her own life, but is prevented just in time by the appearance of her little daughter.
