In the near future, crime will have risen to such a high level that the courts cannot cope any longer if they just use regular law. Instead, prosecutors and attorneys have moved to something called "turnabout law": accuser and defender now have to produce, defend or attack all the evidence within three days, in tournament-like bouts in front of an audience.
Having barely won his first such trial, fledgling attorney Phoenix Wright suddenly gets a huge case dropped in his lap when his boss gets killed and an innocent is framed for the crime. Phoenix sets out to expose the truth and fight for justice, but inadvertently he opens a cesspool where prosecutors leave no dirty trick unused, evidence gets tampered with, witnesses are silenced, ancient cases get reopened and trials lead to more trials.
And that's without even mentioning the ghosts that keep appearing and a Japanese relative of the Loch Ness monster popping up in a nearby lake...
Can Phoenix Wright keep his head above water and his friends out of jail?
