It is the moral obligation of every citizen who is able to do so to make themselves available for jury duty. When Phoebe gets called up, she finds herself one of the twelve who get to sit in judgement on a man accused of murder. Everything is fine until she has premonitions of the real killer and realises that the person on trial is innocent.
The problems begin to arise when she realises that she must prove that the man is innocent and that it's going to be necessary to use magic in order to convince the other jurors. Not exactly an easy task!
There were a nasty group of demons involved in this one as well, but they were a bit boring and the jury part was far more interesting than anything they did.
