Hassan was 10 years old when his father died. His mother died when he was much younger. His late father's employer took pity and took him in under his care and guidance. However, his son Aziz felt envious and soon grew up with ill feelings towards Hassan. When they grew up, Aziz and Buang (Salleh Kamil) often find trouble with Hassan. Salmah fell in love with Hassan which made Aziz even angrier. When II was at Malaya's doorstep, the "Askar Melayu" called for volunteers. Aziz and Hassan responded but Hassan was forced to stay to take care of the plantation by his step father. The village people started calling him a coward. Hassan decided to run away and become a soldier when he couldn't stand the heckling any longer. Hassan proved to be an able soldier and was soon promoted to the rank of Sergeant.
