4d Plays lacking the ne plus ultra, broadcast rarities in the end (7-7)
C-R-A-N -A-S-R-
Can anyone help me parse this please? I'm assuming it's 'Curtain raisers' and that 'the end' is 'Curtains'. That leaves me with 'raiser' which I can see to be an anagram of rarities if you ignore 'it'. Am I on the right lines and, if so, how does 'ne plus ultra' equate with 'it'? Is the clue implying that a play that isn't 'ne plus ultra' hasn't 'got it'?
