In the midst of the French Revolution, unwed mother Marie-Louise Girardin takes one last look at her baby son before entrusting him to her friend, the revolutionary Olympe de Gouges. She must escape, and only the most daring plan will bring her both the anonymity she needs and the independence to return one day for her son.
Marie-Louise disguises herself as a man and joins a voyage of exploration employed as a steward on the Recherche, one of two ships commissioned to journey to the Great Southern Ocean to find the missing explorer La Perouse.
