Lou Clark simply happens to know a lot! She knows the number of footsteps between her home and the bus stop. She knows she loves working at the tea shop called The Buttered Bun and she also knows she might not love her boyfriend Patrick. But what Lou doesn't know is that she is about to lose the tea shop job. On the other hand, Will Traynor knows for a fact that his motorbike mishap has taken away his will to live. He knows that everything feels insignificant and somewhat bleak. He also knows precisely what he will do to stop that. But what Will does not know is that Lou Clark is about to rush into his dull life with an uprising of colours and emotions. They both also don’t know that their lives will never be the same after that.
