A soldier from Mainland China arrives at Hong Kong to look for his estranged sister and finds out that she has been forced into prostitution by a criminal organization.
Frequent Jackie Chan cohort Mars stars as Sing, an ex-con who's supposed to dig up the buried loot of his three still-jailed buddies...but when he gets to it, he finds that the treasure chest is full of rocks! The other three are convinced that Sing stole the goods for himself, so Sing decides to hide out with his kick-butt cousin Kuen, played with athletic aplomb by kung-fu princess Kara Hui! But some insurance investigators (Carina Lau and Billy Lau) are also after the loot, and there's even a mousy travel agent (future director Clarence Fok) thrown in for good measure. It all adds up to numerous shenanigans and action-comedy hijinks, culminating in a knockdown action finale set in a warehouse! Wooden crates, two-by-fours, and more props than you can name are used and abused in the name of creative eighties HK-style action, which Jackie Chan and company are only too glad to dispense to the audience!
Jiaxi Lan
After receiving a life imprisonment sentence for a NY Chinatown massacre, Jia Shi Lan, alias Hei Lan, obtains a pardon through the Mafia's influence. Returning to Hong Kong, Hei Lan attempts to use the stature and fortitude of Brother Han, an elder, but good-natured underworld boss, to gain power and spread the Mafia's influence throughout Southeast Asia. After a deadly double cross leaves many of Han's society dead, two former members, one a cop, the other a florist, and the sole remaining loyalist join forces to bring down the criminal empire of Hei Lan.
