Hot Blooded Youth

It is the early years of the tumultuous Republic of China period of mainland Chinese history (1912–1949). Shanghai is a city divided into a number of jurisdictions, known as Concessions, mostly ruled by foreign powers – and crime is rife.
Amid the chaos, one young man named Wu Qian enters a lucrative but shady competition, in a desperate bid to help his best friend, Wei Cheng Feng, whose grandmother has been struck down by a debilitating illness. However, taking part in this competition proves to be fateful for Wu Qian. He finds himself dragged into a bitter struggle between foreign despots and the local police.
But along the way, he also makes the acquaintance of beautiful, patriotic freedom fighter He Hong Yi, who convinces him that the concessions system should be overthrown. The two are drawn together – only to be wrenched apart by the chaos around them. With overseas tyrants and home-grown crime chiefs all vying for control of the city, Wu Qian and soon He Hong Yi find themselves caught up in a violent and dangerous power play.
