In L.A.'s Chinatown, the crime cartel known as K.O. hatches a plot to bring down Ron Tayan and the 108 Dragons. Ron joins forces with the computer-savvy daughter of the local boss; she tracks the attacking gang via electronics, Ron goes to their stronghold via plane. They are kidnapers of young children, using ransom money to fuel their other activities. The troops are ex-Green Berets; the leaders are Larry Park, an expatriate Yank, and Nina Heaven, a killer with a soft spot in her heart for Ron. He's her captive, but she wants him to be her partner. Meanwhile, Fu, armed with her Muramasa sword, and Dark Eyes arrive on the island surreptitiously. The battle lines are drawn.

Ron Tayan now leads the 108 Dragons; Fu Ching Ran is his loyal wife. As their body tattoos show, he's the dragon, she's the tiger. The 108 Dragons are attacked by African Tusk, a syndicate intent on world control. Ron goes to Africa, dealing first with Shicaro, African Tusk's assassin, then with Jagone, its leader. Despite his success, he must still face Bugnug, Jagone's muscular and athletic military commander: Ron gives her a new name, Dark Eyes. Back in Hong Kong, Fu faces danger as well. A Muramasa sword with a dark history and, seemingly, its own demon spirit, falls into her hands. She seeks to tame it, and in the process, discovers her inner warrior identity

With the blessing of the 108 Dragons, Yo and Emu marry and receive new names, Ron Tayan and Fu Ching Ran. The elders send them to Macau to find out who's behind a new attack. Fu is kidnaped; at the same time, Baya San (the huge granddaughter of the 108 Dragons' aged leaders) demands to be the next head of the gang, not Ron. The childish Baya San has joined forces with the Macau gang, in league with the American mob. A surprise visitor from the US arrives where Fu is being held captive. Can Ron rescue her, find the traitor within the 108 Dragons, defeat his enemies, and bring discipline to Baya San? He must still face the angry and deadly girlfriend of the American visitor.

A formidable assassin is charged by a warden to infiltrate a women's prison to kill the one that took his eye with a knife carved from a spoon: a woman known within the prison walls as The Scorpion.
