Dasie Mea plans to strike it big as a singer of Gospel Music in an all-black New York Baptist Church.
Getting to NYC Daisy Mea learns right away that it's not the wonderful town that she thought it was back in little Perryville Texas when she's saved from ending up working for a local Harlem madam Mamie, as one of her call-girls, by kindly and caring taxi driver Joe Phillips. This happened when Daisy Mea naively goes to the address of a friend of her parents who had long moved out.
Joe getting Daisy Mea a room, room 20, at a local hotel has her fall in with the troupe of entertainers, Moody and his dancing partners Jones and Clementine, who are so impressed with Daisy's beautiful and angelic voice that she's asked by Moody to join their act at the Congo Club. Seeing her chance to make the big time Daisy Mea quickly accepts and becomes an immediate sensation as the troupe's lead singer.
With Daisy Mea not knowing any better she's approached by Arnold Richardson who tells her that as her manager he'll open up doors for her in show business that will make her a top hit not only in the world of Black Gospel Music but will get her a contract with a major record company that will expose her and her music all over the country to millions of people, black and white. What Richardson really wants is to get Daisy Mea into his and his Harlem madam's Mamie stable of call girls. Richardson who tries to make Daisy Mea think that he's in love with her is, unknown to Daisy, married and has been cheating on his old lady who if she ever finds that out would kill him. Joe finding out about Richardson's plans for Daisy Mea in a local newspaper, and knowing that he's married, call's Daisy's sweetheart back in Perryville Texas asking him to come to NYC as soon as possible before his girl, Daisy Mea, ends up in both Richerdson's and Mamie's evil clutches.
Mrs. Richardson finds out about her husband's infidelity at the beauty boutique when she over hears two women talking about Richarson's love life, reported in a neighborhood newspaper gossip column, and goes to his office looking to put a bullet between his eyes but Dunbar and Joe get there first. Richardson all alone with Daisy Mea tries to force himself on her but Dunbar comes to her rescue. In the middle of a knock-down and drag-out brawl an outraged Mrs. Richardson pops in, catching the creep with another women, and takes a shot at the dirty two-timing rat. Mr. Richardson being the bad shot that she is misses her husband but hits Daisy Mea instead with Richardson running for his life and disappearing out of sight never to be seen again in the movie.

Taking Daisy Mea back home to Perryville to get married Dunbar also invites Moody Jones and Clementine to move back home with him and Daisy Mea and live, rent free, happily ever after; You can just guess what Moody & Co, who were always broke and on the verge of getting evicted from their hotel room, answer was.
