Stutterer. Greenwood has a cruel speech impediment but his inner voice is eloquent and witty. He lives and works alone and avoids speaking at all costs. Apart from his ageing father, Greenwood has only one connection to the external world in the form of an online relationship with a girl called Ellie. Every night, often for hours at a time, they exchange messages together. On the eve of their six-month anniversary, Ellie messages Greenwood with the surprise news that she has travelled all the way to London for a few days. She asks him if he would he like to take things “offline” and meet in person for the first time. Greenwood is suddenly facing a truly daunting proposition with everything at stake.
