Male with a plan outside a city (7)
I believe the answer is:
anaheim
'a city' is the definition.
(I have seen 'Californian city' mean 'anaheim' so perhaps 'city' could also mean 'anaheim')
'male with a plan outside' is the wordplay.
'male with' becomes 'he' (I can't justify this - if you can you should give a lot more credence to this answer).
'a' becomes 'an'.
'plan' becomes 'aim' (aiming is a kind of planning).
'outside' is an insertion indicator.
'an'+'aim'='anaim'
'he' put inside 'anaim' is 'ANAHEIM'.
Can you help me to learn more?
(Other definitions for anaheim that I've seen before include "Californian city" , "Disneyland's home" .)
