Charlie, a creative and independent young woman, makes an unexpected discovery on her 18th birthday. Her father isn't the man who is married to her mother. A car drive from Margate to the Isle of Skye to search out her biological father takes her and Oz, a rough sleeper whose only item is his driving license, on an amazing journey. While traveling, they discover more about themselves and each other, the importance of family, and why there is no place like home (at least for a while).
