Mabel, a young woman living in a large mansion, is courted by Tom Darrell, a neighbour of the same class. Meanwhile, Ruth, Mabel’s laundress, is courted by the equally lowly Steve. Ruth and Steve watch the wealthy couple’s courtship enviously. Both couples marry; the Darrells have a daughter, and Ruth and Steve a son and daughter. Tom tires of Mabel and his daughter, and runs away with another woman. Later, Mabel’s little girl is stricken with diphtheria and dies, despite her mother’s offering the doctor all her wealth if he can cure her. Meanwhile, Ruth and Steve’s children remain healthy, and their domestic happiness prevents their persisting envy of Mabel’s wealth from embittering them.
