Like prime numbers, Alice and Mattia are each divisible only by one and themselves: uniquely connected, and forever apart.

Adapted from the bestselling novel of the same name, The Solitude of Prime Numbers traces two decades in the lives of the emotionally scarred Mattia (Luca Marinelli) and Alice (up and comer Alba Rohrwacher, I Am Love) - from the formative traumas of their childhood to the shared loneliness of their adult existence. Essentially isolated, and knowing the other is likewise estranged, Alice and Mattia are ill-suited for romance, yet inexorably attracted to each other.

A simple tale of thwarted love told in a stunningly conceived sequence of flashbacks and jumps forward, The Solitude of Prime Numbers is a powerful and hopeful testament to the slender moments that can forever shape a life.

Also stars Isabella Rossellini as Mattia's mother, and features a score by Mike Patton.
