Allison is in danger at home. Her stepmother has run away and her father is getting worse. So she runs away too and with no where to live finds herself hiding out, miles from home, in an elderly woman's shed. But this woman, Marla, has dementia and doesn't recognise her as Allison, believing she is an old friend from her past called Toffee. So this is who Allison becomes, morphing into a person Marla usually knows and trusts but sometimes fears and fights. As their bond grows, Allison begins to ask herself - where is home? What is a family? And most importantly, who am I, really?
