'ruined' is the definition.
(I've seen this in another clue)

I don't understand how the rest of the clue works.

(Other definitions for shot that I've seen before include "Fired; turn" , "Gunned down - go - guess" , "Attempt; photo" , "Try -- ammunition" , "Small drink; photo" .)

I've seen this clue in The Sun and The Times.
