Yuda is an experienced Silat Harima member (the organization's logo is a tiger head). He lives in a small village called Minangkabau on the west side of the Sumatra Islands in Indonesia. Recently, he has been making final preparations for the Merantau ceremony. This ceremony has been performed in this small village for hundreds of years. After becoming Merantau, Yuda will leave his home in the countryside and his idyllic life. He will come to Jakarta, the capital of Indonesia, to fight for his own world in this prosperous but dirty big city. After a series of setbacks and obstacles, the homeless Yuda feels defeated and confused, and is extremely uncertain about his future. One day, Yuda fought with a group of European criminals to protect an orphan named Astri, and was hunted down by them in revenge. Yuda had to flee with Astri and her young brother. Along the way, they not only had to avoid the European criminals, but also had to deal with all kinds of pimps, hidden gentlemen and gangsters with ulterior motives. Obviously, this was a battle of unequal power, but Yuda had no choice but to fight.
