Partners in Crime (2014) Plot Summary Explained

On an ordinary school day, Huang Li-huai (Wu Chien-ho), a lonely teenager who is regularly bullied by his classmates, discovers the body of a girl lying in an alleyway on his way home from school. Two other students from the same high school arrive at the scene almost simultaneously: Lin Yung-chuan (Cheng Kai-yuan), a quiet straight-A student, and Yeh Yi-kai (Deng Yu-kai), a rebellious bad boy. The three boys, who had never met before, learn that the dead girl was Hsia Wei-chiao (Yao Ai-ning), a withdrawn upper-year student whose death is ruled a suicide after she apparently jumped from her fifth-floor apartment.

Brought together by the incident, the three boys form an unlikely friendship and begin investigating Hsia's death on their own, attending her funeral under false pretences and breaking into her apartment to search for clues. Huang discovers a note written by Hsia to a classmate named Chu Ching-yi (Wen Chen-ling) reading "It's all your fault," leading the boys to conclude that Chu bullied Hsia into taking her own life. They devise a plan to take revenge on Chu by luring her into a forest to frighten her.

After carrying out the plan, the three boys celebrate at a lake near the school, where Huang accidentally drowns. Lin flees the scene in a panic, leaving Yeh to face the aftermath alone. Branded a murderer by Huang's vengeful younger sister Huang Yung-chen (Sunny Hung), Yeh is feared and ostracised by the school. As Yeh remains silent about what happened, an unexpected discovery leads him to uncover a tragic secret kept by his deceased friend, revealing that the truth behind both deaths is more complex than anyone had imagined.
