After being exposed to a mysterious chemical, Sunny transforms into a superhuman mutant along with other circus performers, including his co-worker Angel Chan (Shu Qi) and Sun Hao (Wu Jing). As Sunny struggles to control his new powers, he must evade his former troupe members, who seek to kill him, while also teaming up with a mutant couple, Zheng Xiuhua (Zhang Jingchu) and Sun Hao, to take down his tormentor, Zhang.
