On a hot summer afternoon in New York, Emma Jones gossips with other neighbors in her residential building about the affair that Mrs. Anna Maurrant and the milkman Steve Sankey are having. When the rude and unfriendly Mr. Frank Maurrant arrives, they change the subject. Meanwhile, their teenage daughter Rose Maurrant is being sexually pressured by her married boss Mr. Bert Easter. She does however very much like her kind young Jewish neighbor Sam, who has a serious crush on her.
The next morning, Frank Maurrant tells his wife that he is traveling to Stamford on business. Mrs. Maurrant meets the gentle Sankey in her apartment, but out of the blue Frank comes back home. He realizes his wife is upstairs with Sankey, and runs upstairs. We hear shots and see the two men struggling as Sankey tries to escape through the window. Maurrant runs out with a gun. He has killed Sankey and fatally wounded his wife.
Maurrant is apprehended and is led away by police. He apologizes to his daughter Rose, who will now have to take care of herself and her young brother without either parent. Rose's boss offers once again to set her up in her own apartment, but she refuses. Then she sees Sam, and tells him she wants to leave the city. Sam pleads with her to let him go with her, but she tells him it will be better for the two of them to have a couple of years apart before they consider becoming a couple. Rose walks off down the street by herself.
