A prime number is a lonely thing. It can be divided by only itself or by one; it never truly fits with another. Alice and Mattia are both “primes” – misfits who seem destined to be alone. Haunted by childhood tragedies that mark their lives, they find themselves unable to reach out to anyone else. When the two meet as teenagers, they recognize in each other a kindred, damaged spirit.
