Babe is happy over his engagement to Florence, but the minute he thinks of breaking the news to her mother, Kate, his dream of joy is ended. For Kate's ex-husband was a pugilist and his friends always considered him "some pug," yet at home he was Kate's little lambkin, for Kate carried a wallop in each hand that had a bigger kick than a Krupp gun. Babe thought "safety first" should be his motto; yet, instead of being rough with him when she heard the news, Kate only smothered Babe with hugs. Later, however. Babe meets Ethel, a blonde vampire who drives all thoughts of home and Florence out of Babe's head until the time came to tell Florence that she was no longer a member of the "engagement club." Kate hears the news and her past training with her ex-hubby stands her to good effect until Babe, declaring truce, proclaims Kate the lady of his choice. Trouble begins between Florence and her mother over the possession of Babe. During the melee Babe escapes and seeks safety at the side of Ethel, only to receive an awful blow when he learns Ethel already owns a husband. Then Babe figured, although her mother may be a little rough, it was cheaper to get married than to work, so Babe beats it back to Florence and Kate, where a happy reunion occurs.
