After learning that her boyfriend, Lorenzo (Tristán Ulloa), a talented but troubled writer, may have committed suicide, the beautiful Lucía (Paz Vega) decides to escape to a remote Spanish island. When she arrives, she meets Carlos (Daniel Freire), a scuba diver, and Elena (Najwa Nimri), Lorenzo's former lover. As the twisted story unfolds, Lucía learns more about Lorenzo's tragic past, which may have been the inspiration for his latest novel -- and the root of his depression.
