The fourth film of firefighter-turned-director Yang Shupeng, Blood of Youth follows a young hacker named Su Ang (Oho Ou), who anonymously tips off the police about the remains of a woman buried in the woods near the city of Hangzhou. Detective Zhang (Zhang Yi) discovers the victim was beaten to death almost two decades ago, and starts investigating the events that lead to her death. But at the same time Su Ang also warns the police about a bank robbery about to happen, but just as the robbers led by Shen (Zhou Ziwei) are about to enter the bank, he tips them off too about the presence of the police. His agenda is a mystery, but it may be linked to the fact that a brain injury he sustained during his years in an orphanage is slowly killing him according to his doctor, Han Yu (Yu Nan), especially as he’s not taking the medicine that might save him. And his endgame definitely includes Lin Qiao (Guo Shutong), a young cellist whose libidinous orchestra conductor Li (Guo Xiaodong) is none other than Han Yu’s husband.
