The Big House's "Coloreds Only" policy makes the club popular with Harlem residents. The same policy makes it harder for the owners to find and retain musicians. After four weeks of listening to saxophonists with bigger dreams than talent, the owners are ready to hire the first person who walks in and plays "one good note." Their words come back to haunt them when Randy Jones auditions. Many of the employees are not thrilled when Randy breaks the color barrier. He does find an ally in Cass, the club's sassy singer, who goes out of her way to welcome him. Offstage, Cass Porter looks like a teenager, but when she sings she's all woman. Inside, she's been hurt badly and has determined never to love again. As their relationship develops, life at the club for Randy becomes complicated when he has to fight both Cass's fear of opening her heart and those who want to keep them apart.
