Who would have thought a play about the right way to treat a mental patient could be so fascinating & entertaining. Obviously writer Joe Penhall thought so – as did the audience. The play treads a familiar path (who’s mad - who’s sane) with considerable insight and humour. It raises controversial questions about cultural assumptions and institutional racism.

Chris, a young black guy who believes oranges are blue and that Idi Amin is his father, is nearing the end of a 28 day sectioning. Dr Flaherty believes the current diagnosis of borderline personality disorder masks possibly schizophrenia and that he should not be released. He clashes with Dr Smith, his superior, who trots out the official line of freeing beds.

What follows is a series of powerful, emotional arguments with Chris being used as a shuttlecock. Although bamboozled by the two doctors' technical terminology he is aware of the power struggle. He provokes and exploits the pair to the point where their own saneness is questionable.

Lucy Laing’s direction ensures that tautness is maintained throughout. John Black and Abi McLoughlin gave impressive performances as the warring doctors. Winston Davis’ Chris was superb – eyes bewildered or flashing anger with neurotic body movements never overdone.
