Simon teaches math at an Irish high school and has been haunted by his second-place finish in a Rubik's Cube contest when he was a student nearly 30 years before. When one of his students teases him about being a 'loser' one too many times, Simon sets off to find the boy who beat him and challenge him to a rematch. Along the way, Simon discovers the one thing missing all those years, as romance walks into his life for the first time.
