Broken Blossoms (1919)

Cheng Huan is a missionary whose goal is to bring the teachings of peace by Buddha to the civilized Anglo-Saxons. Upon landing in England, he is quickly disillusioned by the intolerance and apathy of the country. He becomes a storekeeper of a small shop. Through his window, he sees the young Lucy Burrows. She is regularly beaten (by her prize-fighter father), underfed and she wears ragged clothes. Even in this deplorable condition, Cheng can see that she is a priceless beauty and he falls in love with her from afar. On the day that she faints in front of his store, he takes her in and cares for her. With nothing but love in his heart, he dresses her in silks and provides food for her. Still weak, she stays in his shop that night and Cheng watches over her. The peace and happiness that he sees last only until Battling Burrows finds out that his daughter is with a foreigner.
