Draw in a West End plot (7)
I believe the answer is:
attract
'draw in' is the definition.
(synonyms)
'a west end plot' is the wordplay.
'end' says to take the final letters.
'plot' becomes 'tract' (land).
The final letter of 'west' is 't'.
'a'+'t'+'tract'='ATTRACT'
(Other definitions for attract that I've seen before include "Draw towards or get attention of" , "Arouse interest of" , "Lure" , "Exert a pull upon" , "Draw towards, being magnetic" .)
