North General National Hospital in Tondo, Philippines, known as the tertiary hospital, it is the last bastion of Philippine healthcare, accepting all patients overflowing from primary and secondary national hospitals. Within Tondo lies Smoky Mountain, the largest slum in the East, home to tens of thousands of impoverished people. The battle against disease, poverty, and ignorance within this slum is the great mission entrusted to North General National Hospital. Hideyuki Harada is the sole Japanese doctor working in the hospital's obstetrics and gynaecology department. Despite struggling with language and cultural differences, and grieving the death of his lover, he was determined to stand up for the children who, due to poverty, could not receive adequate medical care and were dying.
