Our Young Lions are still idealistic, even heroic. There is nothing world-weary or cynical about them. They want their lives to mean something: they want to make a difference. That's why Donna Parry's headed for the big smoke. But her first day as a city cop is more than she'd counted on when the police station is rocked to its foundations by a convicted cop-killer determined to exact his own vengeance.

Guido Martin wants two things in his life—his job and the woman he loves. He can't have both. And the job is setting him on a collision course with Eddie Mercia whom he accuses of beng involved in a cover-up. Donna and Cameron investigate a series of convenience store robberies committed by two transsexuals.
