Tina Modotti, the controversal Italian communist activist, dies suddenly in a taxi in the wee hours of January 5, 1942. Her still-youthful body awaits an autopsy to determine the cause of her death, which is already a scandal in the press, given Modotti's alleged participation in several political events of this convulsive time: the assassination of her lover Julio Antonio Mella, founder of the Cuban Communist Party; the attempt on the life of Mexican President Pascual Ortiz Rubio, which led to Modotti's deportation; and the plot against Leon Trotsky, the exiled Russian revolutionary. Meanwhile, the coroner's son, an amateur photographer, establishes a bond with the deceased Modotti that will prompt him to spend decades studying her life, work, and final lover, Vittorio Vidali: an agitator and combatant whose crusade, following instructions from Moscow, is to spread Russian influence in a world on the verge of combustion, with fascism on the rise.
