Cup of Life on AllMovie

This picturesque silent adventure was produced by Thomas Ince. Roy Bradley (Niles Welch) grows up in the United States, completely unaware that his father is notorious pearl smuggler "Bully" Brand (Hobart Bosworth). When the young man finishes his education, Brand sends for him but pretends to be his "father's best friend." Brand lives next door to Chan Chang (Tully Marshall), a wealthy dealer who purchases his pearls. Chang's adopted daughter is Pain (Madge Bellamy), a pretty white girl who was orphaned in Singapore at the age of six. Bradley falls in love with Pain, but Chang is determined that she shall not marry one of her race. To get Bradley out of the way, he manipulates him into fighting in a dark room with Brand. During the battle, Brand nearly kills his son before they break though a wall into the light. When he sees that his opponent is his own son, he attacks Chang and makes him promise that Pain will become the boy's wife. He then leaves for parts unknown without revealing his true identity to his son.
