Dope and sex orgy gets uncovered (7)

I believe the answer is:

exposed

I'm a little stuck... Click here to teach me more about this clue!

'uncovered' is the definition.
(I know that uncovered can be written as exposed)

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

Can you help me to learn more?

(Other definitions for exposed that I've seen before include "Unmasked, revealed" , "in the nude" , "Not covered" , "With no protection or shield" , "Laid bare" .)

I've seen this clue in The Globe and Mail.
