It is the big day for the Youngers family, it is moving day. The first thing Ruth does is showing Beneatha the curtains she has bought for their new house.
Walter comes home and dances with Ruth full of excitement and joy. Beneatha teases them about acting in a stereotypical fashion but does not really mean any harm, it was a cheerful moment for them.
Karl Lindner appears at the door (a representative from the Clybourne Park Improvement Association), and tells the Youngers that problems arise when different kinds of people do not sit down and talk to each other. He also reveals that their presence in Clybourne Park would destroy the community there since the residents are all white.
Ruth, Beneatha, and Walter all become very upset Walter firmly tells Mr. Lindner to leave immediately.
Mama comes home, Walter, Ruth, and Beneatha tell her about Mr. Lindner’s visit. It shocks and worries her, but she supports their decision to refuse the buyout offer.
Bobo, Walter’s friends announces that Willy Harris has run off with all of the money that Walter invested in the liquor store deal. It turns out that Walter had invested not only his $3,500 but also the $3,000 intended for Beneatha’s education. Mama, is now really worried.
