As a member of the Sarawak Constabulary, he fights to protect his people, but when the Japanese invade during World War II, Ujang is forced to make impossible choices. Amidst the chaos, he finds love in the fiery and fearless Dayang, a woman who becomes his anchor in a world falling apart. But when Dayang is captured by the enemy, Ujang's loyalty is tested like never before.
