Underworld drug king Toplar is flooding the market with low-grade heroin. Agent 99 gets a bit too close to the truth, but manages to gasp out a clue as to the identity of Toplar: he has a scar. Jane (Agent 73) is called in to find Toplar, and gets a camera implanted in her breast in order to photograph the bad guys she dispatches so headquarters will be able to identify Toplar when she finds him. Meanwhile she begins falling in love with fellow agent Jim.

After the mob hits a guy with a list, one of the hoods keeps the list to blackmail its inhabitants. When he’s found out to be a double-crosser, they off him, angering his busty girlfriend. She goes after them using the only two weapons she has.
