The Convict Killer (1980)
After spending fifteen years behind bars for a crime he didn't commit, Teng Piao is released, shackled by his past and driven by a thirst for vengeance. His target is Lam Fei, known as Black Leopard, but Teng faces a challenge: he has no idea what his nemesis looks like, only that Lam bears a distinctive tattoo of a black leopard on his chest. Armed with his iron chain and a determination to uncover the truth, Teng embarks on a relentless quest to find the man responsible for his wrongful imprisonment.
