Father Timothy Bottoms is investigating possible corruption in the archdiocese at the order of the Archbishop. Novice Michele Greene has been assisting him. As he finds disturbing signs of corruption, rumors about a sexual relationship between the two swirl. When she is called to his hotel room, she finds an unknown priest there. He gives her a drink of sherry and she falls asleep. When she wakes, Bottoms' corpse is found, and she finds herself on trial for the priest's murder. Good thing that Raymond Burr is at hand when she is taken into custody and that he is Perry Mason.
Of course there are several other suspects, mostly having to do with the corruption issues, and when they're on the witness stand, you know that the least likely one will confess. In the meantime, there's the story of Miss Greene's character and her uncertainty about whether to take her final vows. It's a bit reminiscent of the movie A NUN'S STORY and makes the TV movie seem derivative. Still, there's always the fun of watching Raymond Burr in his signature role.
