Hartoyo and Sanusi, who had been friends since they were TNI, registered themselves as development soldiers to be sent to Harapan Island. Sanusi's younger sister, Aesah, was Hartoyo's girlfriend. Sanusi's mother passed away and then Sanusi also passed away. This made Aesah like someone who had lost her memory, wandering "along Malioboro". Luckily Hartono returned and looked for Aesah.
