A huge dragon banner unfolds, declaring war. People panic: men sharpen hatchets; shops are shuttered. Wong Low Get (Edward G. Robinson) is summoned from Sacramento to take revenge for Hop's death. He is stunned when the council president, Nog Hong Fah (Dudley Digges), tells him that Sun Yat Ming (J. Carrol Naish), his friend since childhood, is the guilty party. Sun is surprised and pleased to see Wong. He has prepared for his own assassination: His will leaves everything to his old friend. He also asks Wong to raise his little daughter, Toya San, and marry her when she comes of age. Wong agrees—and then reveals that he is the Lem Sing Tong hatchet man. Wong swears before the Buddha that Toya will never know “the song of sorrow.” Sun calmly kneels and prays and forgives Wong's “innocent hand its stroke of justice.”
