Dressing up as a maid, Ann obtains a position in Hargrave's apartment and sets about seducing him, even suggesting that he kiss her in order to be able to write about romance more convincingly.
Ann discovers that Hargrave's mother (Dunbar) is pushing him into a marriage with Evangeline (Morse), an intellectual but plain young woman.
To save him from this unwanted marriage, Ann plants certain items of scanty feminine attire about Hargrave's bedroom, and when Evangeline finds these she promptly calls off the engagement.
Hargrave learns of Ann's role at the paper, and, knowing that she is responsible for the end of his engagement, demands that she leave his premises.
When she promises not to publish the information she has obtained about his private life, and convinces him of her true feelings, he forgives her, and all ends happily.
