A Hong Kong cop finds himself up to his neck in trouble when he encounters a tricky bunch of crooks and triads.

Triad member Michael Chan Wai-man decides to leave his gang and go straight. But this decision doesn't sit well with his gang leader, who sees Chan's actions as a betrayal and decides to frame him for a series of violent murders. Now the ex-gangster must clear his name and stop the violence.

A young suitor loses his girlfriend to a wealthy businessman. At first he's angry. Then in a fit of depression, he goes to the sea shore where he finds lizards. Immediately he puts the lizards into a bag and takes them home. Then he becomes obsessed with ladies dirty underwear and he steals six or seven "tainted" ones from public restrooms and brothels. At this point the man mixes the juices from the underwear with a special "aggressive compound" and then injects the fluid into the lizards. The little reptiles (now hooked on "love juice") become soldiers in his personal battle against females. "I hate women!" he screams, holding helpless victim's legs apart allowing the little creatures to gain entrance. Lots of women die, driven mad with sexual ecstasy and pain, while the misogynist psycho howls with laughter.

A wronged female ghost is out for revenge.

羅馬、張揚合導的《阿牛入城記》以阿牛（野峰）這個大鄉里來到香港，目睹香港低下層社會的光怪陸離，有悲有喜，有血有淚。阿牛生性戇直常常被人利用，周大叔（王沙）帶他做賭檔「睇水」，他以為是看著一桶水，大出洋相。阿牛做過很多工作，不時被壞份子利用如幫人「捉黃雞」勒索、到城寨做「阿牛艷舞」等，但阿牛的天真純樸仍得到阿花的喜愛，反映傳統社會的善良信念：天無絕人之路。後來，阿牛到碼頭做苦力，工人罷工，他繼績工作，竟然被打，阿牛自衛釀成大騷動，被拉入獄。結局無疑令人悲哀，卻反映編導的聰明之處，留下尾巴，讓關心阿牛命運的觀眾期待下集《阿牛出獄記》登場。

《军阀趣史》（The Scandalous Warlord）是由李翰祥执导，艾飞、陈菁、强汉等人主演的一部喜剧片。影片于1979年2月9日在香港上映。影片讲述了庞大虎之后又一位山东军阀的故事。 本片可以看做《大军阀》的续篇， 讲述庞大虎之后又一位山东军阀的轶闻趣事，连智审风化案、给老太爷祝寿、军阀姨太偷情等桥段都大同小异。 不过，较之《大军阀》的包罗万象、正谐兼备，这次《军阀趣史》的情节主要集中在风流韵事上，查暗娼、访私娼，叔嫂通奸、姨太偷情，一路香艳到底，胡锦、邵音音、余莎莉、楚湘云等一班艳星各展风情，自然噱头十足。

年青演员甘国亮，独挑大樑，主演「蛇杀手」，演绎这个沉鬱又受社会歧视的变态青年，可谓入木三分。香港电影史上，以蛇杀人为题材，可谓绝无仅有，更难得导演桂治洪大卖血腥暴力之餘，又能成功刻划一个善良青年转变为杀人狂魔的过程，导演桂治洪大卖血腥暴力，凸显蛇杀人的惊心场面，技法出眾。人蛇之间的友谊，相当感人。最后一场，群蛇围堵大屋，肆意狂咬。最后一场，群蛇围堵大屋，肆意狂咬，为香港电影史上其中最噁心动魄一幕。
