Regularly working alone undercover with a vice squad boss she dislikes as much as he dislikes her, Lottie Mason is living pretty much on the edge. An assignment helping out the Assistant D.A. may be the start of a serious relationship but then, tired and disillusioned after a job one night, she finds herself accepting a proposition in a bar that leads rapidly into a web of murder and deceit.

Ellie DeWitt and Janis Zuckermann are admitted to the very strict FBI Training Academy. They get a hard course, in which they learn to deal with guns and to recognise crimes. They also get a physical training. It appears that Ellie is a real fighting- machine, in contrast with Janis, the great student. They have to help each other, all the way to graduation.
