Leon has a small visible mechanical heart; Kathryn has been cured of a rare genetic disorder but is now covered in curly black wool; while performance artist Christos has metal wings implanted into his back. Brought together by a canny entrepreneur, 'The Wonders' are transformed into a glamorous, genre-defying, twenty-first century freak show. But what makes them objects of fascination also places them in danger.
