Judicial and public opinion differs into conflict over a bereaved father who killed to avenge his daughter's death.

Deed comes under pressure to acquit a man charged with a serious assault on his wife because the man could provide vital information about the IRA.

When a rich and well-connected boss blames his underlings for a death, John Deed takes up the cause; Deed's daughter, an animal rights activist, liberates a dog from a lab, subjecting herself to blackmail attempts.

A rapist convicted by Deed is released from prison and sets out for revenge; after initially harassing Deed, he then turns his attention to the judge's daughter.

Deed fights a never ending battle with corruption within the legal system, while his amorous adventures keep him busy; Deed acquits a young female doctor accused of killing an elderly patient whose will is written in her favour.
