Six years after Lorenzo (whose name means "sun," played by Tristan Ulloa) swam with Elena (Najwa Nimri) on an island brilliant with moonlight, he is living with Lucia (rising star Paz Vega, whose performance here earned her the Goya -- the Spanish Oscar -- for Best Actress). Through flashbacks, Julie Medem's Sex and Lucia jumps to their first, bizarre meeting, where Lucia, the girl with the question mark smile, flings herself at Lorenzo after declaring that she is a fan of his novel.
