《特攻聯盟》首集(由亞倫•強森和克蘿伊摩蕾茲主演)的成功賣座造就了席捲全球，由星條旗上校(金凱瑞飾)帶領的凡人英雄聯盟的風潮。這次紅霧俠(克里斯多福米茲布拉斯飾)將全面追殺他們，只有超犀利的超殺女(克蘿伊摩蕾茲飾)能夠挽救這場屠殺行動。
After Kick-Ass' (Aaron Taylor-Johnson) insane bravery inspires a new wave of self-made masked crusaders, led by Colonel Stars and Stripes (Jim Carrey), our hero joins them on patrol. When these amateur superheroes are hunted down by Red Mist (Christopher Mintz-Plasse), only the blade-wielding Hit Girl (Chloë Grace Moretz) can prevent their annihilation.
