The college boy, Bob, comes home after a four years' absence. Immediately he calls up his friends Betty and Brownie and their mother, a typical society matron. Bob tells them he is coming right over. Consternation reigns. It is the maid's afternoon out and they could not so far belittle themselves as to open the door. So the little slavey, Ella, is pressed into service. Awkward, shy, inquisitive, she greets the visitor, who is amused and interested in her. Again he sees the little maid and something neither can explain draws them together. The night of the big masked ball arrives. The mother and her daughters go as Bob's guests. The little slavey in her old clothes is left at home. She finds an extra costume and decides wildly to brave the danger. Decking herself out she attends the ball, but the shoes of the sisters are too large for her and she is forced to wear her own old ones. Bob finds the unknown woman at the ball and is strangely attracted to her. They, well, you know the rest...
