The last supper:

The Last Supper is an inspirational musical theater work that tells the
story of the creation of Leonardo da Vinci's great masterpiece. Actors
portray Leonardo, Jesus, the twelve Apostles and two women, while
singers express the meaning and emotion of the action through song.

Leonardo has been commissioned to create a mural of The Last Supper,
his first attempt at painting in ten years. He fears he has lost his artistic
vision by squandering his gifts. An angel/muse inspires him to invoke
the Apostles and ultimately the Last Supper. By discovering what each
individual was thinking and feeling at the moment of crisis, Leonardo
confronts his own betrayal and learns that through love and faith he can
rediscover the vision of divine inspiration and the purpose of life.
