Iris has always wanted to meet the famous boy band, one direction. But when she is diagnosed with Cancer at age 16, she fears that it will never happen. Without her knowing, on her 18th birthday, her best friend Haley post a picture of her on Twitter, the caption of the picture informs that Iris has cancer and her dying wish is to meet One Direction. Luckily, a member of the band, sees this post and makes her wish come true. She stays in touch with all of the boys for a while, until one of them starts to fall for the beautiful, young girl, but when they start to talk more often, he finds out that life's not quite that easy for her, yet he promises that he will always be there for her, but 'Promise' is a big word, it could either make something or break everything.
