It's never too late to grow up... This is the story of: Scott, who finds his belongings outside in a bin bag one day and realises he may have made a Big Mistake; Gail, who wishes her husband were under guarantee so she could send him back and get a refund; Nat, who discovers that growing up isn't all it's cracked up to be; Rosie, who just wants her Dad back - or if not, then at least some new glitter nail polish. Four lives, one story: love, loss and learning to be a grown-up.
