Shinjuku Incident

In the 1990s, due to the economic crisis in China, thousands of Chinese people moved to Japan in search of work. One of these illegal migrants, Chietu, nicknamed "Steelhead," left his home country to find his girlfriend, Xu Xu, who had gone to work but never returned. Without money or documents, Chietu joined a gang of illegal immigrants like himself. Eventually, he found his beloved, but she was now the wife of an influential yakuza who refused to let her go.
