A dying teacher instructs his final student to check on the activities of five former pupils, each of whom he taught a unique and special style of kung-fu to: The Centipede, Snake, Scorpion, Lizard, and Toad (hence the title). His final student, who knows a little of each style must team up with one of the other good students to destroy the evil ones if there are any. Greed and treachery ensue as the student discovers that some of the students are indeed evil. But which one can he trust enough to team up with? 残缺的五毒，世界真美好。五种人，五种毒，鲜明的人物性格特点，比最近这些年所谓的大片不知道强了多少。五毒－一部虎头蛇尾的悬疑片（旧作）。葫芦娃夺宝记。张四代。此片 卫矛 高档。人过招，笑藏刀。暴力美学下的怪诞。从《五毒》与《残缺》看张彻表现的思想人生。漏洞百出。 五毒门乃江湖上一恶名远扬的门派，老掌门靠药浴维系残年，身边只有一个弟子杨得（江生 饰）。有感本门恶事作尽，老掌门命杨得清理本门门户，并寻找其师叔的宝藏。杨得的五位师兄分别习练五种由毒虫而来的武功，分别是：蜈蚣（鹿峰 饰）、蛇（韦白 饰）、蝎子（孙建 饰）、壁虎（郭追 饰）、蛤蟆（罗莽 饰）。 杨得乔装成乞儿，迤逦打探到一座县城，巧遇隐姓埋名的师叔老夫子一家遭人灭门，凶手正是大师兄与二师兄，虽然本县何捕头凭习练蛤蟆功的五师兄助拳将大师兄拿获，但县令与二师兄勾结反将五师兄下狱害死。三师兄时常蒙面夜会二师兄，掌控全局于幕后。 杨得发现何捕头即四师兄后向对方亮明身份，两人决定合力清除大师兄二师兄。暗处的三师兄决定出手了……
