A faction vows to ruin Mr. Gibson’s wedding to Rosie Turner, citing an old family rivalry and mocking her 'cheap' dress. They storm the venue to force the engagement canceled, while a messenger relays Mr. Gibson’s grandfather praising Rosie as virtuous and beautiful. The pressure scatters the guests; Mrs. Gibson refuses to call it off. Confronted, Rosie—the flower girl—snaps, "Get lost." With the mob gone and expectations collapsing, Mr. Gibson faces calling off the engagement himself but is stunned by Rosie's beauty, leaving his decision unresolved.
