SYNOPSIS

On the eve of her 25th birthday, Catherine, a troubled young woman, confronts how she has spent years caring for her brilliant and unstable father Robert, a famous mathematician.

Now, following his death, she must deal with her own volatile emotions, the arrival of her estranged sister Claire, and the attentions of Hal, a former student of her father's who hopes to find valuable work in the 103 notebooks that her father left behind.

Over the long weekend that follows, a budding romance and the discovery of a mysterious notebook draw Catherine into the most difficult problem of all: How much of her father's madness—or genius—will she inherit?
