Her mother died when she was four years old; her surrogate mother abandoned her a few years later, plunging Thérèse Martin (Lindsay Younce
) into a mental collapse. Then something miraculous happens. At the age of 14 she undergoes a mysterious conversion and falls deeply in love with God. Then -- not old enough for the convent -- she goes all the way to the Vatican, where she boldly steps forth at a papal audience to beg for permission to become a Carmelite nun.
In the monastery, Thérèse, a teenage girl, gains insights that breathe fresh air into the Catholic Church and transform the world. Challenged by the austere, cloistered life, this pampered child discovers a simple way of loving God.
