Madrid, in the forties. In the post-war period, Paca, a chorus girl who aspires to enter the Celia Gámez Company, returns to Madrid after a provincial tour. In the same train travels Luis, undocumented young person to whom Paca allows him to spend the night in the room where she lives with her sick father. Paca's relationship with Julio, a mogul without remorse, offers her financial support, but Luis gives her the tenderness and love she does not have with Julio.
