The Nameless revolves around the story of a man named Lai Teck, one of the 50 known aliases of the Secretary-General of the Malayan Communist party from 1939 to 1949. Lai Teck's real name and background have never been confirmed, but evidence suggests that he was born in Vietnam to a Chinese mother and served as a spy to both the French and British. Piecing together found footage from several Hong Kong films starring actor Tony Leung Chiu-wai, The Nameless acts as a fragmentary portrait of Lai Teck, the film star's likeness standing in for the ambiguous political figure. Ominous and shadowy, the film features Leung (as Lai) in times of distress and introspection, interspersed with repeated motifs of smoke, water, torture and death.
