Petru's Candle is based on A Christmas Tale, written by Queen Marie of Romania. Petru, a little boy living in a poor Romanian village fears the worst for his mother's health, so he sets off to light a candle in a church as an offering in order for her to recuperate. On the way, he chooses to give his candle to a lost soul who speaks to him from the bottom of a well. It turns out to be an angel, who assures him his mother is recovered because of his sacrifice to a soul in need.
