Lou Clark knows how many footsteps there are between the bus stop and home. She knows she likes working in a tea shop and she knows she might not love her boyfriend Patrick. What Lou doesn't know is she's about to lose her job or that knowing what's coming is what keeps her sane.   Will Traynor knows his motorcycle accident took away his desire to live. He knows exactly how he's going to put a stop to that. What Will doesn't know is that Lou is about to burst into his world in a riot of color. And neither of them knows they're going to change each other for all time.
