A research lab has developed "The Formula", a box that allows living organic material to grow hundreds of times its original size. Criminals invade the lab to steal it, but it's thrown off the side of the road. There it's found by a girl who decides it will be the perfect home for Mosler, the snake she has adopted. Mosler immediately outgrows the box, springing to the ground like a pile of novelty dog poo. Gang members see the girl and her huge snake frolicking outside and put two and two together. Mosler thwarts their first attempt to snatch her, but when they do succeed he goes on a rampage trying to find his friend
Ma Tung-choi
In realising their scheme to rule the underworld, the Poisonous Snake Gang breeds the 'Blue Poisonous Bees' and sends Red Rose over to the blue-clad Flying Dragon Gang to execute the 'Flying Sting' mission. Shadowed by the competent fighter Lung King-tin, Ma Tung-choi demands that the newcomer obtain the nuclear pistol from Poisonous Snake to prove her loyalty. Anna Tai of the Female Monster Gang intercepts the two and makes them yield the pistol before locking them up. Upon Lung's heroic rescue, Rose shifts loyalty to Flying Dragon but the Poisonous Snake spies strike, abducting the three to a garage where a brawl breaks out. Armed with the pistol, Anna frees the captives. She bestows the pistol on Flying Dragon as a token of goodwill, putting behind her unrequited love for Ma who loves only Rose. Poisonous Snake launches a raid on Flying Dragon only to be wiped out by the deadly bees that they breed but fail to contain.
