Johnny Lovo rises to the head of the bootlegging crime syndicate on the south side of Chicago following the murder of former head, Big Louis Costillo. Johnny contracted Big Louis' bodyguard, Tony Camonte, to make the hit on his boss. Tony becomes Johnny's second in command, and is not averse to killing anyone who gets in his and Johnny's way. As Tony is thinking bigger than Johnny and is not afraid of anyone or anything, Tony increasingly makes decisions on his own instead of following Johnny's orders, especially in not treading on the north side run by an Irish gang led by a man named O'Hara, of whom Johnny is afraid. Tony's murder spree increases, he taking out anyone who stands in his and Johnny's way of absolute control on the south side, and in Tony's view absolute control of the entire city. Tony's actions place an unspoken strain between Tony and Johnny to the point of the two knowing that they can't exist in their idealized world with the other. Tony's ultimate downfall may be one of two women in his life: Poppy, Johnny's girlfriend to who Tony is attracted; and Tony's eighteen year old sister, Cesca, who is self-professed to be older mentally than her years much to Tony's chagrin, he who will do anything to protect her innocence. Cesca ultimately comes to the realization that she is a lot more similar to her brother than she first imagined. 将类型片拍成艺术的霍华德 · 霍克斯。黑帮片之祖。《疤面人》（1932）两个不同版本结局。全能类型片之王霍华德霍克斯。20世纪初的美国“旧式神话”的存亡战斗。刀疤所暗藏的多重隐痛。《疤面人》看完豆友們影評的筆記。控制一切，被反噬。毁灭。摘录。 本片讲述了二十年代着名的芝加哥犯罪头目疤面人自崛起至暴毙的故事。全片以阿尔卡邦的生平为蓝本，再加上一名有乱伦关系的妹妹，越发使内容显得复杂而敏感，在当年是具有重大影响力的犯罪片之一。导演霍华德．霍克斯力求使全片看起来生动耀眼，暴力镜头有跃出银幕之感，主角保罗．茂尼的演出亦光芒四射，为类型电影的经典之作。
