Within the walls of a cloistered convent, two nuns are discovered, one dead, one critically injured - victims of a seemingly motiveless, brutally savage attack. Dr. Maura Isles and detective Jane Rizzoli, find themselves part of an investigation that leads to an awful, dawning realisation of the killer's identity.
