Isabel Clifford sits to be painted. Her artist is Marion Leslie, a man distracted by matters of the flesh. Not Isabel’s flesh but Lorelei’s, the same Lorelei who wows the corrupt police chief, Sarpina, with her virtuoso vocal performances. She is Mexico’s most celebrated opera diva, Marion’s fiancé, and Sarpina’s passion, yet she boils with petty suspicion over Marion’s friendship with Isabel.
