People coming back see as a result of this instruction? (9)

'people coming back' is the definition.
(people who are returning)

'see as a result of this instruction?' is the wordplay.
I cannot quite see how this works, but
an anagram of 'see' is 'ees' which is located in the answer.
The remaining letters 'return' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
