Simone de Beauvoir reimagines the dance between consciousness and the world outside in a Rouen café. Ayn Rand labours in Hollywood exile on the novel she believes destined to reignite the flame of liberty in her adoptive nation. Simone Weil, disenchanted with the revolution's course in Russia, devotes her entire being to the plight of the oppressed. Over the next decade, one of the darkest in Europe's history, these four philosophers will conceive in parallel ideas that would circle the globe in the second half of the century, reshaping it.
