Chaz Wilmot's father is a famous illustration artist, in the vein of Norman Rockwell. Chaz has inherited his skill and has surpassed him and is in fact, an artistic genius. With a very ill son and an estranged wife whom he still loves but cannot provide for financially, Chaz accepts a commission to 'restore' an antique fresco in a European castle.
