Gyeong-seon, a tough, tanktop-wearing dame is a cab driver who's quite capable of beating up troublesome passengers. Su-jin in permanent shades and trashy clothes is the girlfriend of a punk gangster, Bulldog. The two dames first meet when Su-jin accidentally crashes her car into Gyeong-seon's taxi after a row with Bulldog, who runs the betting on cage fights (generally between dogs) for his boss, Kim Geum-bok. The women hardly hit it off, and they each have their own personal problems: Gyeong-seon is being hassled by loan sharks for repayment of a debt incurred by her AWOL ex-husband; Su-jin, who dreams of being a pop singer in Japan, is routinely slapped around by the psychotic Bulldog. After Gyeong-seon is beat up by the loan sharks, she finally agrees to go into business with Su-jin, who has the idea of having fake cops raid the cage-fighting joint, and snatching the evening's booty in the ensuing chaos. Gyeong-seon is to be the getaway driver, but on the night, Su-jin appears to double-cross everybody, including her femme partner, with rather bloody results.
