Joe hosts a farewell party for a worker who is retiring, and Brenda and Nick attend with Rhoda. Nick tells them he plans to leave New York because he is not getting jobs. Brenda asks Joe to hire him at his demolition company.
Rhoda has invited a couple of gal pals over, but when Myrna shows up, she is canceling to go out with a man she just met. Rhoda decides the gals should go out by themselves one night to prove they do not need men to have a good time.
Brenda's friend Sandy asks to move in with her because the commute to work would be shorter. Brenda agrees and they work things out. But then Sandy asks a co-worker to move in as well, and then there are three in the small apartment.
Washington, DC based FBI agent Michael Stearns makes what most consider an unreasonable request: to move into Brenda's apartment for an indefinite period of time (meaning that she would have to find other accommodation for that time) while he does some surveillance work on an apartment across the street. Brenda agrees if only because she is attracted to Michael. Insecure Brenda, who ends up staying with a cold plagued Rhoda and Joe upstairs, makes any excuse she can to go to her apartment just so that she can see Michael. He doesn't mind as he too is attracted to her....
Martin is restless and bored with his life. Ida thinks he is having an affair. One night when Martin again leaves for the evening without an explanation, Ida, Rhoda and Brenda follow him. They find he has a new interest - playing piano.
