A biography of St. Maria Faustyna Kowalska. Helena Kowalska was born in 1905 and as a child she was very religious and dreamed of entering a convent. As a teenage girl she could join the convent but she had to bring a dowry which was mandatory at that time. Young Helena leaves her family house and finds a job as a maid. She saves every penny for her modest dowry. Eventually, Mother Superior agrees to take her to the convent. Contrary to expectations Helena, now as sister Faustyna, experiences a huge disappointment in the Congregation of the Sisters of Our Lady of Mercy. It turns out that the monastery is a place not only for mortification, fasting, and performing good deeds but also for envy, pettiness, pride and laziness. Against all ods, Faustyna decides to stay in the Congregation and her faith is invincible. She has visions, she feels the presence of Christ, she talks with him. Faustyna prays fervently and works beyond her strength. When she is 33 year-old she goes down with tuberculosis and dies.
