Mystic Faces (1918)

Yano is a small delivery boy for his uncle, who keeps a curio shop in Chinatown. His loves are Tama, his sweetheart, and Bengi, his dog. Bengi is seized by dog catchers, but is rescued by Letty Stanford, for which Yano promises his fealty. Later Letty is kidnapped by Germans because of her war activities, and it is Yano who goes to her rescue and gets her free in spite of his diminutive size. The Little Japanese has paid his debt.
