Luke Hemmings is a homeless boy living on the streets of London. He has been alone for so long, he's forgotten what it's like to have a friend. What it's like to have someone actually care for you, to care about you. That is until Ashton Irwin, a 19 year old with a teenage girl giggle, stumbles into his life. Ashton shares a house with his school friends Michael Clifford and Calum Hood, and when he finds Luke out on the cold streets, he helps give him a home. After all those years of being ignored by everyone who passes him, Luke isn't used to human interaction and doesn't fit in well with the boys. Will Ashton be able to help Luke, or will Luke stay cold forever?
