It's Christmas in Finglas once again but no-one in the Brown household has got the memo. Mrs Brown can't seem to please anyone - Betty is annoyed with her for giving Bono money, Mark is annoyed at his mum for not listening to Betty, Winnie thinks Agnes doesn't care about her and Cathy think she's too nosy. It might almost be better if Agnes had never been born. Enter Clyde, who says he's an angel. Maybe he could grant Agnes her wish, to show her what life would be like if she'd never been born? Agnes scoffs but before she knows it she's in a world she doesn't recognise and that doesn't recognise her. A world where her family is someone else's and she must come to terms with a life she never knew...
